Bars

In civil engineering, bars refer to steel reinforcement bars or rebars. These are structural members primarily used for reinforcement purposes in masonry works. A bar is characterized by its cross-sectional area, which is negligible compared to its length. Bars are usually manufactured by steel which is uniform throughout the length, or by meshing multiple steel wires. Other materials of the bar include carbon steel, glass fiber, carbon fiber, and basalt fiber. The reinforcing bars are coated with epoxy resins and other materials to enhance some of their properties including corrosion resistance.

This is a Mechanics of Materials Problem. I have been able to find the force at yielding but do not know where to go from there.
An aluminum alloy [E = 10,000 ksi; σY = 40 ksi] pipe (1) is connected to a bronze [E = 16,000 ksi; σY = 45 ksi] pipe at flange B. The pipes are attached to rigid supports at A and C. Pipe (1) has an outside diameter of 2.150 in., a wall thickness of 0.16 in., and a length of L1 = 6 ft. Pipe (2) has an outside diameter of 5.10 in., a wall thickness of 0.19 in., and a length of L2 = 10 ft. If a minimum factor of safety of 1.6 is required for each pipe, determine:(a) the maximum load P that may be applied at flange B.(b) the deflection of flange B at the load determined in part (a). Deflection to the right is positive.
By inspection, determine the zero-force members in each truss. Identify the zero-force member by placing an “X” through that member. If you need to do this iteratively, and redraw the truss without the zero-force members you have already found, you may do so.
