For a bronze alloy, the stress at which plastic deformation begins is 274 MPa and the modulus of elasticity is 112 GPa. (a) What is the maximum load that may be applied to a specimen having a cross-sectional area of 338 mm2 without plastic deformation? (b) If the original specimen length is 106 mm, what is the maximum length to which it may be stretched without causing plastic deformation?
