A 10 ft long rectangular ASTM A572 Grade 50 steel plate 1 in. by 12 in. in cross section is used as a hanger and subjected to a tensile load of 240,000 lb. The proportional limit of the steel is assumed to be 45,000 psi. Compute a) axial stress, b) axial strain, c) transverse strain, d) total axial dimensional change and e) total transverse (12 in. side) dimensional change.
