  • Your response should be at least three paragraphs (with four sentences per paragraph).

my post is :

 

Maxwell's  Equations state that in a static electric field, the divergence at one  point equals to the electric charge volume density at that point divided  by a magnetic field. Necessarily, it implies that a rotating magnetic  field is produced by an electric current or by an electric field that  changes with time (Rahm, 2008). Also, it says that a changing magnetic  field that changes with time produces an electric field. In essence, the  Equations consist of three other equations such as Gauss, Faraday, and  Ampere equations.

Maxwell’s  equations in real life can be applied in the explanation of the physics  of permanent magnets. It leads to the formulas generating magnetic  surface currents that describe the generation of the magnetic field as  well as how magnets retain magnetism status. The equations help in the  explanation of how the radio frequency waves propagate that lead to  communications of all kinds to occur with radio signals and TV  transmitters (Rahm, 2008). Besides, the equation explains how the light  in the visible regions is capable of creating things like interference  patterns that have several usages in optical technology.

Maxwell's  Equations explains the antenna can be designed to get the best signal  which is essential for a cell phone that uses radio waves. Play of video  games using a computer is made possible because of the equation since  it involves changing of electric and magnetic fields (Ishimaru, 2017).  Besides, it is applied in the design of a microwave since it helps in  knowing where the fields are strong or weak. Finally, the equation  allows engineers to know the weight that can make a bridge to crash into  the river.

The  advancement of technology has created another essential use of  Maxwell’s Equations, especially in the health sector. The equation has  used in the determination of how body organs produce bioelectric  signals. The purpose of electrocardiography, electroencephalography, and  electromyography use Maxwell’s Equations in checking of the diseases in  different parts of the body (Ishimaru, 2017). Therefore, it is  projected that the equation would be used in providing more details  about diseases of the brain, heart, and muscles.

Skin Effect on Transmission Lines

The skin effect describes the tendency for AC current to concentrate  on the outside of a conductor. As the intensity of the current changes  inside the conductor, it produces a magnetic field that rotates  perpendicular to the electromotive force. This magnetic field naturally  resists the change in current and radiates from the middle of the  conductor. This counter-electromotive force pushes the current towards  the edges of the conductor and increases its effective resistance as the  current is bottle necked by the magnetic field.

Skin depth describes the depth of the current density from the  outside of the conductor. This property depends on the frequency of  transmission and the conductors electric and magnetic permeabilities.  The total current that a conductor can handle will decreases  exponentially as the skin depth narrows. This effect has serious  implications for both high frequency and high-power applications alike.

Here is an example of how the skin effect can cause problems with  efficiency: At 20 KHz, the 12 AWG (d=0.093”) wire will use 75% of the  conductor, while the 10 AWG (d=0.115”) wire will only use 68%. This loss  in efficiency forces designers to pay close attention to sizing that  best suits their frequency of operation. Some of the real-world  applications include audio system engineering, long distance  transmission, and RF circuits.  

AC transmission has been consistently redesigned since its  introduction in the late 1800’s. Today, our transmission lines are  created by wrapping interlocking copper strips around a hollow core.  This structure reduces the weight of the wire, the cost of copper, and  strength of the transmission towers. The problem is that engineers are  fighting the publics insatiable need for power with incremental  technological gains. AC transmission is limited by the skin effect  combined with cost of materials. One of the exciting new developments in  this field is that engineers are reinvesting in the idea of long  distance direct current transmission.

High Voltage Direct Current (HVDC) is an example of future  applications that attempt to circumvent the limitations of the skin  effect. One of the major issues regarding this application is the  regulation of continuous current flow. A direct lightning strike on this  kind of transmission can cause massive breakdowns in infrastructure,  and engineers are diligently working to provide an effective circuit  breaker to protect against this kind of problem. Once these kinds of  problems are ironed out, we might someday see DC transmission become the  leader in long distance transmission.

For this part of assignment, I selected equation that describes  behavior of electric charge when Electric field is applied. Equation is  F= qE. This equation interests me at this point because it can be linked  to mechanical world with concept known as force. While we cannot  typically benefit from just E-field, we do benefit from effect of  electric field on the charges. Sizable amount of E field converted to  current used in systems that convert Electric energy into mechanical  energy. Hence relationship or link from Electric force to Mechanical  force. Unfortunately, this seemingly direct link jeopardized by energy  transfer loss that known as concept of efficiency.

   Electrons are particles in conductive material. Electrons are  charge particles that can transfer energy from one end of wire to  another. For energy transfer to occur, electric field must be applied.  Each electron has constant, determined experimentally and theoretically  amount of charge equal to 1.6E-19 C. When conductor appear in constant  E-field all free electron will be forced to edges of conductor such that  sides opposite charges of the E-field source and receiving conductor  will balance out. In case of varying polarity or direction of the  E-field we will observe change of the polarity in the conductors that  happen to be in the E- field. Now what selected equation is actually  states is that strength of the E-field will have greater effect on the  electrons. This effect of the E field on electrons humans defined as a  force.

One application for this equation is in design of electric motors.  Electric motors conceptually are as follows. Charged particles in  conductor (electrons) when moving, create Electric field that excites in  mechanically free to move object charged particles that move to align  with current carrying conductor. Charged particles in the object will be  motivated to align faster and in the end with greater force when  E-field is stronger. Greater E-field creates greater magnetic field  which in turn induces E-field. Mechanisms designed to align fields in  desired direction of motion and with consideration of aligning  perpendicularly to E-field and parallel to magnetic field. This creates  class of electromechanical devices.

Application of electric force has expanded during last century  exponentially. And yet we are not anywhere close to limit of  applications to this charming phenomenon. On example of growing  application of Electric force is ability to wirelessly transfer energy  on short distances. For consumer application notably would be desire of  automotive industry to use higher voltage circuits. In considerations  are power circuit with 48Vand higher. This potentially allows for  smaller wire gages for the same amount of power transfer.

 

3)

 

Considering the equation  where  U is the potential energy in units of J (Joules); q is the charge of a  particle in units of C (Coulombs) and V is the electric potential in  units of J/C (Joules per Coulomb); we can say that a positive particle  at some distance away from a negative particle has a certain degree of  potential energy. The same can be said for gravitational potential  energy. 

Regarding gravity, PE is energy that is  being stored by an objects position; energy was put into the object or  moved to its position; for every action there is an equal in opposite  reaction thus, we have potential. The PE equation for gravity is very  similar to the electric potential equation where .  

Potential difference is everything. When  designing circuitry, electric potential is always accounted for as to  not overdrive any of the components. Additional, if the circuits  requirements are using higher potential differences, the components are  to be adjusted as such (i.e. higher power ratings).

As for real world applications,  simulation software does a pretty good job at presenting data that  assists in any design process. The electric potential can be viewed per  node and adjustments can be made accordingly. Electric potential will be  around forever, and any future technologies will require the use of the  idea of electric potential.  

Describe how your equation relates to the equation posted.

Mandy took a trip to Rome, Italy. She gazed out over the open ocean 20,000 feet below as her airplane began its descent to her final destination of Rome. It had been a long flight from New York to Rome, but she as she stretched, and her bones creaked as though she was old, she knew that in fact, she was a tiny bit younger than her compatriots back home, thanks to traveling at hundreds of miles per hour. In fact, time for her was running slowly compared to her friends in New York for two reasons: the speed at which she had traveled and the height of the airplane above the Earth. Neither, though, were noticeable.

Research Proposal

HPE 578

Overview: Write a research proposal. Basically this is the first half of a research paper where you prepare to start collecting data. Thus, you will not actually conduct the research so there are no results to present or discuss.

Guidelines:

1.      APA formatting

2.      Minimum of 2500 words, excluding the reference section

3.      Minimum of 8 primary sources

4.      Follow the provided template, “Dallas Baptist Template”

Suggested steps:

Step 1 – Choose a general topic.

Step 2 – Search the databases and start reading relevant articles.

Step 3 – Identify a problem of a “gap” in the literature. Narrow in on a specific research area of interest to you. You will probably need to locate more sources at this point.

Step 4 – Write the introduction. Some authors write the introduction as a separate chapter from the lit review and others combined them. For the sake of this assignment, you will keep them separate like the provided template (Dallas Baptist Template) shows. Here you will include the problem statement, purpose statement and hypothesis or research questions. You may or may not discuss a relevant theoretical framework. If you are performing a qualitative and/or survey study, it is likely you will discuss the theoretical framework.

Step 5 – Methods Section. Not necessarily in this order, but you should discuss the following:

·         Design

·         Procedures

·         Subjects

·         Instrumentation

·         Data analysis – I suggest you keep this simple. Identify a few variables and do you best to select the appropriate statistical tests (if warranted). This is not a stats class and I know this is new to many of you so simple do you best and feel free to call or email for help. The flow chart at the end of chapter 14 is a good starting point.

Step 6 – Proof read and edit, compile your references section and check in safe assign to be 100% sure that you did not plagiarize.

Step 7 – Write the abstract and proof read again.

Resources:

See the resource folder for this assignment and use your text book.

Tips:

·         Read the entire articles so you get a good feel for the research process. Only reading the abstracts will limit your understanding.

·         Remember to write in future tense sense you have not conducted the research yet. For example, “the subjects’ body fat will be measured with calipers…”

·         Use a referencing tool to help you keep track of your sources, it will also make the writing stage much easier as you insert parenthetical citations and compile the reference list.

·         Write like the authors in the example articles. Clear and to the point – try to avoid slang, contractions, unnecessary words and phrases, and first person references. See some examples below:

No: Smith (2003) took into consideration the young students’ desire to play

Yes: Smith (2003) considered the children’s’ desire to play

No: In these modern times, children today simply want to spend hour upon hour endlessly playing video games.

Yes: The current generation spends a great amount of time playing video games.

No: I will weight each participant with a balance scale.

Yes: participants will be weighed on a balance scale. Or Researchers will weight participants with a balance scale.

The following articles were given to me by instructor to facilitate getting started on proposal, so make sure to use the references below in addition to any other scholarly peer review references … Thanks!!!

BALANCED TORQUES AND CENTER OF GRAVITY

Objectives:

To study and understand the conditions for static equilibrium in a plane and to study the experimental concept of center of gravity.

Overview:

In this lab you will examine the conditions for static equilibrium and explore the nature of Center of Gravity and Center of Mass. In addition you will explore the concepts of rotational and translational equilibrium and torque. Torque is defined as the product of force times distance and its units are Newton-meter or foot Ibs.

Important Note #1: For this lab we will define Force to be solely the mass of the object in grams and distance to be in centimeters. This means that the units for torque, for this lab only, will be gram-centimeters, g.cm.

EXPERIMENT A: CONDITIONS NEEDED FOR EQUILIBRIUM

STEP 1: Set up the arrangement shown in the figure below to study the conditions for equilibrium.

STEP 2: Balance the meter stick system (i.e., with all the attachments) and record the balancing position as the position of the fulcrum.

STEP 3: Select two different size masses (more then 100 grams including the mass of the hanger) and using the string loops, suspend each one on either side of the fulcrum. Adjust the positions of each suspended mass until the meter stick is balanced once again. Record the masses used and their positions at the time when balance is achieved. Compute the clockwise and counter-clockwise torques and compute the percent difference. [Percent difference is defined as 100 times the difference in the two values of torque divided by one of the torque values]

Important Note #2. For all parts of this lab, your percent difference must be below 1 . If they are not redo the procedure.


 

2

Put the answers to all questions that follow in the lab report.

QUESTION 1 a]. Does the condition for rotational equilibrium hold? b]. What could account for the discrepancies?

QUESTION 2 a]. What would you have to do to the set-up to produce translation without rotation? b]. Figure out three ways to cause a rotational imbalance.

QUESTION 3: Is there more than one way to arrange the two weights and still achieve balance?

STEP 4: Now suspend two unequal masses [more then 100 grams] at different positions on one side of the fulcrum and one on the other side of the fulcrum.

Important Note #3: Don't put the masses too close to the fulcrum.

Compute the clockwise and counter-clockwise torques and the percent difference and record the masses and positions once balance is achieved.

QUESTION 4: Does equilibrium depend on the number of forces pulling on either side of the fulcrum?

QUESTION 5: Does the condition for rotational equilibrium hold?

STEP 5: Use the arrangement in step 3 to balance the meter stick with one known mass and another unknown mass. Record the positions and known mass.

QUESTION 6 a]. Is it possible to use the balancing system to calculate the unknown weight? b]. Explain how this might be done and compute the unknown weight.

EXPERIMENT B: WEIGHT OF THE BAR AND CENTER OF GRA VITY

STEP 6: Use the arrangement in Step 1 to balance the meter stick using one known mass (above 100 grams) on one end and no mass on the other end. You will have to move the fulcrum in order to balance the meter stick.

QUESTION 7: What do you think provides the torque on the end without a weight that balances the meter stick?

QUESTION 8: What position is this mysterious force located that balances out the meter stick?

STEP 7: Assume that the mass of the meter stick, W, is uniform. Use the conditions for equilibrium to compute the

mass of the meter stick and compare this value to the measured mass of the meter stick. SHOW THIS COMPUTATION IN THE DATA PORTION OF YOUR REPORT.

STEP 8: Now tape a mass, such as a strip of lead, near one end of the meter stick. This arrangement will act as a loaded [non-uniform] meter stick. Find the mass of the loaded meter stick using a laboratory scale. Keep the load mass on the stick for the remainder of the experiment.

STEP 9: The center of gravity of this new loaded stick is at some arbitrary point C. Using the knife-edge once again, balance the meter stick and find the position of the fulcrum.

c


 

3

STEP 10: Suspend a mass as shown in the figure and adjust the position of the knife edge until balance is achieved. Record all necessary information.

A

B

c

STEP 11: Determine the value of L, the moment arm of the mass Wl, and find xcalculaled. the moment arm of the loaded meter stick by balancing clockwise and counterclockwise torques. Determine Xmeasured by measuring the distance between the new fulcrum and the center of gravity of the loaded meter stick.

The following problem is to be solved and included in your report in a section title Problems after the Conclusions section.

Problem: Find the center of gravity relative to the front axle of a van with 130 inch wheel base where the weight on the front tires is 2100 Ib and the weight on the rear tires is 1800 lb. Keep your answer in inches and pounds and show your calculations.

ABET Outcome: Students will demonstrate their ability to complete this comprehensive project based on knowledge and skills acquired in earlier course work.Students will also demonstrate their ability to deliver recommendations effectively in written communications. {SHM-23; ABET-(g)}

Project:Capstone Insurance provides a wide range of “commercial business” insurance products and risk management solutions for mid-sized and large businesses. Upon your graduation from Central, you are hired by Capstone Insurance. Your first task is to assess the safety performance of a potential client, a medium sized light truck and utility vehicle manufacturing company (North American Industrial Classification System Code [NAICS]336112).This company has never had a good safety program, and has never filled out OSHA 300 logs. They just lost their insurance with another carrier. Your manager provides you with a list of accidents / incidents, which the company experienced in 2016. She assigns you the following tasks:

1.      Compare the company’s recordable/DART rates to the national average rates.

 

a.       You have to classify each of the accidents / incidents into one of the eight injury/incident categories:

                                i.      Non-work related (NWR)

                              ii.      First Aid (FA)

                            iii.      Recordable – job transfer cases

                            iv.      Recordable – restrictions cases

                              v.      Recordable – other cases

                            vi.      Days away cases

                          vii.      Environmental incidents (EI)

                        viii.      Others

 

b.      Use the 29 CFR 1904 OSHA recordkeeping requirements (www.osha.gov) to identify the OSHA recordable injuries.

 

c.       Fill out the federal OSHA 300 log for applicable injuries. Use the injury IDs provided on the injury table for each injury. You can make up employee names. Use the online MS Excel version of the 300 log (OSHA website).In addition, fill out the OSHA 300A summary sheet based on the injury information and work hours provided in Table 1.

 

d.      Analyze the accident / incident data with the help of a MS Excelworksheet. Create the Table 1 provided below in MS Excel sheet with built-in formulas.

                                i.      Calculate the first aid, recordable, and DART ratesper 100 full-time workers for each month using work hours provided below.

                              ii.      Find out the recordable and DART rate industry average for NAICS 336112 from the OSHA website.

                            iii.      Create a line graph comparing the company’s average to the industryaveragefor recordable and DART rates.

                            iv.      Make sure to add additional columns for environmental and other incidents.

 

2.      Create accident trending charts using MS Excel for Capstone Corporation using the accidentlog presented in Table 2. Provide detailed corrective actions.

 

a.       Feed injury / incidentclassification (e.g., first aid, recordable, environmental incidents, etc.) information from item1(a).

 

b.      Classify the injury types under: Bruise, Sprain, Strain, Fracture, Laceration/Cut, Burn, Puncture, and others.

 

c.       Classify the accident type under: struck-by, struck-against, contact-by, contact-with, caught-on, caught-in, caught-between, fall-to-surface, fall-to-below, exertion, bodily reaction, and exposure.

 

d.      Classify the body part.

 

e.       Create seven professional graphs for: (1) OSHA classification, (2) injury days, (3) injury time zones, (4) accident type, (5) body part, (6) supervisor, and (7) Area.For injury time, split the time into four zones (e.g., Zone 1: 6 am to noon).

 

f.       Include the trends in your report and identify remedial measures.

 

3.      Recommend a Corrective Action Plan (CAP) and an Accident Prevention Plan (APP):

 

Your manager wants your recommendation. Should Capstone InsuranceCompanyinsureCapstone Corporation after this detailed review?

 

                    i.            If no, provide a detailed explanation justifying your decision.

                  ii.            If yes, why, and what is the CAPyou would want to see from Capstone Corporation as a condition of providing insurance?

                iii.            Provide recommendations for the company to create a workplace APP, including environmental management. If this company is located in Washington, what would be the major elements of the company’s APP? Develop the list based on the accidents / incidents suffered by the company and Washington Division of Occupational Safety and Health (DOSH) requirements? What should each element address based on the company’s injury history (provide at least one sentence explanation for each element)?

 

4.      Report Submission:

 

a.       Hardcopy: Submit your overallreport that includes your recommendation, injury summarylog and accident trend summarylog, and completed OSHA 300 and 300A log.
