4-6. The assembly consists of an A-36 steel rod CB and a 6061-T6 aluminum rod BA, each having a diameter of 1 in. Determine the applied loads P₁ and P2 if A is displaced 0.08 in. to the right and B is displaced 0.02 in. to the left when the loads are applied. The unstretched length of each segment is shown in the figure. Neglect the size of the connections at B and C, and assume that they are rigid. C B 2 ft P2 4 ft A Pi
