The results of a tensile experiment on a metal is given in the table below. The tensile sample had circular cross section with the diameter of 10 mm and initial gauge length of 60 mm. Use this table and calculate:

Force (N)	Measured Length (mm)	Region
0	60	Elastic
15708	60.15	Elastic
31416	60.3	Elastic
35343	60.6	Plastic
36128	61.2	Plastic
36914	63	Plastic
37306	66	Plastic

(a) The Young modulus of this metal (in GPa)

(b) The modulus of resilience (MJ/m3 )

(c) The measured diameter of the sample is 9.5mm when the applied force is 37306N. What is the Poisson’s ratio?

(d) What is the engineering stress and strain, as well as the true stress and strain at the applied force of 37306N?

Expert Solution

DETAILED SOLUTION

FINAL ANSWER

(a) E = 80 Gpa

(c) Poisson's Ratio = 0.5

(d) Engeering Stress = 474.9951 MPa

Engineering Strain = 0.1

True Stress = 522.4946 MPa

True Strain = 0.0953

Physics problem Assume that you did the experiment described below, and obtained the given results. P1- You had a spring with a rest length of 27.5 cm. You let the spring hang from a stand, so that one of its ends was attached to the stand, while the other end was free. You then let loads of different masses hang from the free end of the spring. The loads’ masses were 500 g, 1000 g, 1500 g, 2000 g, and...

A single crystal of a metal is oriented for a tensile test such that its slip plane normal makes an angle of 64.2° with the tensile axis. Three possible slip directions make angles of 30°, 48°, and 78° with the same tensile axis. (a) Which of these three slip directions is most favored? (b) If plastic deformation begins at a tensile stress of 1.6 MPa (232.1 psi), determine the critical resolved shear stress for this metal

2.) The tensile strength of a metal is a measure of its ability to resist tearing when it is pulled lengthwise. To see if a new experimental method of treating steel bars improves tensile strength, random samples of bars treated using the experimental method and treated using the old method are taken and the tensile strengths are measured and recorded (in newtons per square millimeter). Assume both populations are approximately normally distributed. Experimental Method: 362 382 368 398 381 391...
