As a material scientist, you have been requested by an engineer to list down a possible cylindrical rod alloy to be used in your next project. Each cylindrical rod having a dimension of 100 mm long and a diameter of 10.0 mm is to be deformed using a tensile load of 27,500 N. It must not experience either plastic deformation or a diameter reduction of more than 7.5 × 10−3 mm. Based on materials listed in Table 2, which are possible candidates? Justify your choice(s).

You have been given the following test sample data following mechanical testing of 15 test pieces of a transformation toughened zirconia. What is the Weibull modulus of this material? Would you advise the use of this material over one with a Weibull Modulus of 25.4 and a mean failure stress of 235 MPa, if you anticipate that the peak stress on the material could be 220 MPa? (Since this question has two parts, you must select the two correct options from the list below) Test Sample Failure Stress (MPa) 1 255 2 271 3 260 4 223 5 257 6. 267 7 242 8 230 9. 245 10 225 11 254 12 236 13 238 14 251 15 264 O a. 27.3 O b. 4.5 O c. 6.9 O d.

Q1/A structural part is 1-meter-long and subjected to a 50 KN load in which this part must be deformed elastically without experiencing any permanent deformation. If you know that part is made of steel, brass, aluminum, and Titanium alloys and the yield strengths and densities of these alloys are: 860 MPa, 7.9 g/cm³; 415 MPa, 8.5g/cm³; 310 MPa, 2.7 g/cm³; and 550 MPa, 4.5 g/cm³ respectively. Based on these criteria, rank the alloys from the heaviest to the lightest in weight.

Based on the stress-strain plots, which materials tested are stiff and which are tough? How can you tell the difference? * we tested (Steel HR250)and (Aluminium 5251)in this experiment

You are given three metal test samples, with the same chemical composition and differing grain sizes: A: 5.0, B: 10.0 and C: 20.0 microns. Samples A and B have been tested and have yield stresses of 142.4 MPa and 135.8 MPa (all numbers are rounded off to the 1st decimal point). Based on this information, which of the following values do you think will be the closest to the yield stress of Sample C? In calculating the answer, use the Hall-Petch relation between yield stress of a metal o vield and the grain size of the metal d, which is Oyield = 00 + kd¬1/2 where k and og are constants. (This question has only one correct answer) а. 100.6 MPa b. 131.1 MPa С. 152.4 MPa O d. 115.8 MPa е. 128.1 MPa

Define a homogeneous material?

In designing a ceramic part for a jet engine, to ensure that the part does not fail, we plan to ensure that the maximum applied stress is only one-third of the yield strength. The yield strength of this CMC part for a jet engine is 520 MPa, and its plane strain fracture toughness is 5.5 MPa√?. We utilize a nondestructive test to find any internal faults that are longer than 1.27 mm. Does our non-destructive test have the requisite sensitivity if Y = 1.4? Explain.
