The stress–strain relationship shown in Figure P1.16 was obtained during the tensile test of an aluminum alloy specimen.
Determine the following:
a. Young’s modulus within the linear portion
b. Tangent modulus at a stress of 45,000 psi
c. Yield stress using an offset of 0.002 strain
d. If the yield stress in part c is considered failure stress, what is the maximum working stress to be applied to this material if a factor of safety of 1.5 is used?
