A circular steel rod AB of diameter d = 0.60 in. is stretched tightly between two supports so that initially the tensile stress in the rod is 10 ksi (see figure). An axial force P is then applied to the rod at an intermediate location C.
(a) Determine the plastic load PP if the material is elastoplastic with yield stress σY = 36 ksi.
(b) How is PP changed if the initial tensile stress is doubled to 20 ksi?
