- A rigid plate C is used to transfer a 20-kip load P to a steel (E = 30,000 ksi) rod A and to an aluminum alloy (E = 10,000 ksi) pipe B as shown. The supports at the top of the rod and the bottom of the pipe are rigid, and the materials were unstressed before the load was applied. The cross-sectional areas of rods A and pipe B are 0.80 in2 and 3.00 in2 respectively. Determine The normal stress in rod A in ksi, The normal stress in pipe B in ksi and The displacement of plate C in inches.
