Mechanics of Materials Lab

i have uploaded all the data you will need for the lab. also i have uploaded sample old answers for similar lab which is 80% same to the lab that need to be done. please make sure to check the numbers because there are few diffrnces between the old and the my lab. also, make sure to paraphrase everything.

Electrical engineer

5 hp, 60 Hz, connected in Y, with the following parameters in ohms per phase referred to the stator circuit: R1 = 0.641; X1 = 1.106; R2 = 0.332; X2 = 0.464; XM = 26.3. The mechanical speed of the rotor shaft is 1760 r / min. Find a) The losses in the copper of the stator b) Power in the air gap c) Converted power and d) motor efficiency.


Load 1 is a 6000 W three-phase star connected motor with a power factor of 0.6. Load 2 is a balanced three-phase load with Zf = 20 ∟-36.9 Ω. Find the total current in each line, the apparent power, reactive power and the losses in the copper that the factory requires.

Then post what you thought was the most important concept(s), method(s), term(s), and/or any other thing that you felt was worthy of your understanding in each assigned textbook chapter.Your initial post should be based upon the assigned reading for the week, so the textbook should be a source listed in your reference section and cited within the body of the text. Other sources are not required but feel free to use them if they aid in your discussion.
Also, provide a graduate-level response to each of the following questions:
Find a recent news article on an ongoing project, evaluate the management’s performance, and explain how the project could be better organized and managed.
Discuss the pros and cons of the spiral project life-cycle model and the waterfall project life-cycle model. How are the processes in the PMBOK related to each other? Give a specific example.
2)Find an article describing a national project in detail. On the basis of the article and on your understanding of the project, answer the questions below. State any assumptions that you feel are necessary to provide answers.
Who were the stakeholders?
Was it an internal or external project?
What were the most important resources used in the project? Explain.
What were the needs and expectations of each stakeholder?
What are the alternative approaches for this project?
Was the approach selected for the project the best, in your opinion? Explain.
What were the risks in the project?
Rank the risks according to severity.
What was done or could have been done to mitigate those risks?
Was the project a success? Why?
Was there enough outsourcing in the project? Explain.
What lessons can be learned from this project?
The assignment is to answer the question provided above in essay form. This is to be in narrative form and should be as thorough as possible. Bullet points should not to be used. The paper should be at least 1.5 – 2 pages in length, Times New Roman 12-pt font, double-spaced, 1 inch margins and utilizing at least one outside scholarly or professional source related to project management. The textbook should also be utilized. Do not insert excess line spacing. APA formatting and citation should be used.

gantt charter

2- I did one before and the professor comment was”Inappropriate gantt chart.
Dates on the x-axis are in incorrect formats
The task bars in the chart shown should have different starting points to reflect different starting dates.”
3- I want know the correct one, then I want updated for it till today date which is (7-9-2021)

Mechanics question (Quick)

The angle that the slat makes with the horizontal is α, known and fixed. The particle falls due to the force of gravity and experiences a viscous friction due to air proportional to the speed of the particle, that is, f_roc = βv, and a sliding friction, with a known static friction coefficient μ_k.
a) Taking the reference system inclined with zero at the base of the plane, calculate the velocity of the particle considering that it starts from rest (5 points).
b) Now the system rotates in the plane of the sheet, counterclockwise, with a known constant angular velocity ω. Find the equations of motion of the particle in the non-inertial frame of reference. (5 pts)
c) Solve the differential equation for the position of the particle in the non-inertial referential with the initial conditions ρ (0) = L and ρ ̇ (0) = 0 (5pts)

Appendix # 3

Problems for the text: Required for Activity 9 in Week 11
1.A researcher is asked to determine whether or not a productivity objective (in dollars) of better than $75,000 per employee is possible. A productivity test is done involving 20 employees. What conclusion would you reach? The sales results are as follows:
2.Assume you have the following results from sample data:
S = 30, n = 64, and sample mean = 218.
Conduct a two-tailed hypothesis test for
H0: µ =200 at the 0.05 significance level.
3.A researcher hypothesizes that 15 percent of the people in a test-market will recall seeing a particular advertisement. In a sample of 1,200 people, 20 percent say they recall the ad. Perform a hypothesis test.

MATLAB-Mathematical Modeling of Thermal Systems

The inside of the room is at temperature 𝑇𝑟and the walls are assumed to be at temperature 𝑇𝑤.

If the outside temperature is 𝑇𝑜, develop a model of the system to show the relationship between the supplied heat 𝑞 and the room temperature 𝑇𝑟
Write the state-space model of the system in a matrix form and solve this equation using MATLAB. Plot the figures showing temperature variation for this thermal system in terms of 𝑇𝑟 vs. 𝑡 and 𝑇𝑤 vs. 𝑡 (𝑡𝑖𝑚𝑒). (Assume that 𝑅𝑟=0.5, 𝑅𝑤=1.8, 𝑇𝑟=8, 𝑇𝑤=4, 𝑇𝑜=3, and 𝑞=10)
Produce this assignment in a report format, with additional explanations on :
