MSE 3005 Mechanical Behavior of Materials Spring 2021 Quiz #1 – (25 Points Total) Version A Page 2 of 2 3. (10 Points) You have been asked to test a cylindrical tensile specimen that has a diameter of 5 mm and a gage length of 25 mm. The specimen is made of a polycrystalline aluminum alloy (elastic modulus, E
, of 69 GPa and an Poisson’s ratio,
, of 0.27). Calculate the gage length of the specimen when it is loaded to its proportional limit limit if the yield strength of the alloy is 250 MPa.

Please double check before rejecting this question. If it needs to be rejected, please explain why as I cannot see how this is a breach of the honor code.
This is a questions from the previous year's exam at my university in Engineering Science. I have submitted a solution given to us for study purposes as proof that I will not be graded on this assessment.
In this solution, the formula (2gh)1/2 is used to find the solution, but I am on familliar with Bernoulli's Principle (P=1/2pv^2+pgh), and I was not able to find a solution using this. My solution incurred an error when I found that I had two unkown variables left that I could not break down in any meaningful way. (Velocity being the desired variable, Pressure being the problematic variable). Pressure = Force x Area, but I don't know enough about the dimensions of the tank or tap to be able to understand this.
Thank you for your help.

What is the major drawback of the Merit index?
Select one:
O a. The merit index can consider only one criterion at a time
O b. It is useful only for forming a subjective value of a material
O c. The algebra is too hard to be performed successfully
O d. There are no drawbacks to the Merit index

Set up a spreadsheet solution to this problem. This will require that you derive one
formula to express the relationship between the friction coefficient, the spring constant,
and the spring compression; and a second formula to find the cost of using different slide
and spring types. Set up your spreadsheet as shown below. You can fill in the
"Acceptable?" column manually, rather than using a formula. Turn in a copy of your
spreadsheet/Matlab work

You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture
fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates
implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial
weight bearing activities.
Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to
verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into
solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending
test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the
yield stress for the Ti-6Al-4V…
