Question

For a bronze alloy, the stress at which plastic deformation begins is 275 MPa and the modulus of elasticity is 115 GPa. (6 marks - 3 marks each part) (a) What is the maximum load that may be applied to a specimen with a cross-sectional area of325 without plastic deformation? (b) If the original specimen length is 115 mm, what is the maximum length to which it may be stretched without causing plastic deformation?
