Part a and b I need to show all work

Qu 10 A cylindrical metal specimen 15.0 mm in diameter and 150 mm long is to be subjected to a tensile stress of 50 MPa; at this stress level, the resulting deformation will be totally elastic. (a) If the elongation must be less than 0.072 mm, which of the metals in Table | are suitable candidates? (b) If, in addition, the maximum permissible diameter decrease is 2.3 x 10 mm when the tensile stress of 50 MPa is applied, which of the metals that satisfy the criterion in part (a) are suitable candidates?
