1.The flow curve for a certain metal has parameters: strain-hardening exponent is 0.22 and strength coefficient is54,000 lb/in2 . Determine:
a) the true stress at a true strain = 0.45
b) the true strain at a true stress = 40,000 lb/in2.
2.Determine the reactions on the beam. The support at B can beassumed to be a roller.
