General Instructions Upload Matlab files for Assignment 8 to the appropriate link on Blackboard. Upload final Matlab files (YourINITIALSfilename.m), separately. Print program flowcharts, listings (a copy of the Matlab code) and requested sample runs, and submit each on the due date. Deliverables: For each program submit a flowchart, listing of the code, a sample run and the program’s Matlab (.m) file.

Problems: 1. The “filename” in YourINITIALSfilename.m for this program is “cylinder”. Create a flowchart and a corresponding Matlab program that outputs a hollow cylinder’s inner diameter, surface area and volume when a user enters cylinder height (h), outer diameter (d) and inner diameter as a percentage (p) of outer diameter. This program must prompt the user to accept any reasonable value for height, outer diameter and percentage (0-100%). In the submitted file after the listing for the final program, provide the results for one sample run of the program with h = 1 in, d = 2 in and p = 50%.

Air enters the compressor of an ideal air-standard Brayton cycle at 100 kPa, 300 K, with a volumetric flow rate of 5 m3/s. The turbine inlet temperature is 1800 K. For a compressor pressure ratio of 9, determine: (a) the percent thermal efficiency of the cycle. (b) the back work ratio. (c) the net power developed, in kW.

Problem 1:

Carry out the first three iterations of the solution of the following set of equations using the Gauss Seidel iterative method.Provide the solution using a program, you are free to use any language including MATLAB.

8x₁+2x₂+3x₃ = 51

2x₁+5x₂+x₃ = 23

-3x₁+x₂+6x₃ = 20

What negative effects have resulted from the material changes? Consider the full material life cycle.

Would it actually be more sustainable from an environmental, economic, and/or social perspective to return to materials that were used in the past? Why or why not?

As a lab instructor in machining, you are required to prepare a lab module for a
laboratory session with your students. In this session, the students are required to
produce aT-Slot. Prepare the methodology to produce the T -Slot with
illustrations for the lab module.

During a drilling process, excessive drill wear and drill breakage may occur. As
an experienced machinist, you are required to investigate the probable causes
which lead to these problems and suggest on how to solve these issue.

Identify 5 benefits of using a Database management systems

You have just started work at an aircraft engineering company and have been tasked with a complex engine change on the aircraft.

What kind on negative reactions could this cause in you? And what could you do to reduce these negative reactions?

Explain different types of car suspension systems.

what is the difference between analytical solution and FEA??

The total cycle time of an automated fiber placement (AFP) operation (sheet lamination), used to manufacture a section of the airplane fuselage, is 8 hours and 40 minutes. The setup time before the start of the operation is 10 minutes. After each layer is put down, an inspection stage is performed for 5 minutes. The AFP head requires cleaning cycle of 3 minutes every 7 layers.

1. If the part is made of 20 layers, what is the time required (in minutes) to lay down 1 layer? (40 points)

2. What is the percentage of down time for this operation? (30 points)

3. What is the total cycle time (in minutes) for making this part, if the lay down speed was doubled? (30 points)

Air enters a horizontal, constant-diameter heating duct operating at steady state at 280 K, 1 bar, with a volumetric flow rate of 0.25 m³/s, and exits at 325 K, 0.95 bar. The flow area is 0.05 m².


Assuming the ideal gas model with k = 1.4 for the air, determine:

(a) the mass flow rate, in kg/s,

(b) the velocity at the inlet and exit, each in m/s, and

(c) the rate of heat transfer to the air, in kW
