Question

The assembly consists of two-rod brass C83400 copper alloy rods AB and CD of diameter 30 mm, a stainless 304 steel alloy rods EF and FG of diameter 40 mm, and a rigid cap H as shown in Figure 2. Neglect the size of the collar at F. Assume that the modulus of elasticity E_steel = 200 GPa and E_brass = 101 GPa. If the force, P = 5 kN,

(a) Sketch the free body diagram and calculate the internal forces acting in each section of the rod.
(b) Determine the average normal stress developed in rods FG, EF and AB.
(c) Determine the average normal strain in the rod of AB.
(d) If the horizontal displacement of end G of rod FG is 0.6 mm, determine the new magnitude of P.
