(a) phi = 20 degree, and (b) phi = 45 degree. 2 The engineering stress - strain diagram for tension specimen of structural steel is shown below, determine the following properties at appropriate: a. Modulus of elasticity.
b. Yield point.
C. Yield strength.
d. Upper yield point.
e. Lower yield point.
f. Modulus of resilience.
g. Ultimate tensile strength. h.
