E-073. The assembly shown in Figure P5.9 consists of rod (1) and tube (2), both made of steel (E= 30,000 ksi). The tube is attached to a fixed support at C. A rigid end plate is welded to the tube at B, and the rod is welded to the end plate. The rod is solid with a diameter of d₁ = 0.375 in. The tube has an outside diameter of D2 = 2.25 in. and a wall thickness of t₂ = 0.125 in. The dimensions of the assembly are a = 60 in. and b = 32 in.
