1. The A992 steel rod is subjected to the loading shown. If the cross-sectional area of the rod is 60 mm2, determine the displacement of B and A, Neglect the size of the couplings at B, C, and D.
2. The assembly consists of two 10-mm diameter red brass C83400 copper rods AB and CD, a 15-mm diameter 304 stainless steel rod EF, and a rigid bar G. If P = 5 kN, determine the horizontal displacement of end F of rod FF.
3. The load is supported by the four 304 stainless steel wires that are connected to the rigid members AB and DC Determine the vertical displacement of the 500-lb load if the members were originally horizontal when the load was applied. Each wire has a cross-sectional area of 0.025 in2.
4. Bone material has a stress-strain diagram that can be defined by the relation a = E[61(1 + kEE)J, where k and E are constants. Determine the compression within the length L of the bone, where it is assumed the cross-sectional area A of the bone is constant.
5. Determine the support reactions at the rigid supports A and C. The material has a modulus of elasticity of E.
