Question

Find the solution for each part

A) In the tensile and wood experiments, you learned about the stress-strain behaviors of different materials. Sketch a thoroughly labeled stress-strain diagram to explain the mechanical properties of 1) window glass, 2) copper metal, 3) annealed copper metal. Make sure to have all three curves on the same plot. Please label the x and y-axis, and the different mechanical parameters (Ultimate Tensile Strength, Yield Stress, Rupture Stress and Modulus of Elasticity).

B) Hookes law is only applicable in the plastic region of the stress-strain curve. (True/False)

C) Polymers are more ductile than ceramics. (True/False)
