For a bronze alloy, the stress at which plastic deformation begins is 275 mpa (40,000 psi), and the modulus of elasticity is 115 gpa (16.7 * 106 psi). (a) what is the maximum load that may be applied to a specimen with a cross-sectional area of 325 mm2 (0.5 in.2 ) without plastic deformation? (b) if the original specimen length is 115 mm (4.5 what is the maximum length to which it may be stretched without causing plastic deformation?
