2.) Answer the following: a.) a 22 ft long solid steel rod is subjected to a load of 15,000 lb. This load causes the rod to stretch 0.435 in. The modulus of elasticity of the steel is 30,000,000 psi. Determine the diameter of the rod. b.) A solid circular titanium control rod must support an axial tension force of 12,000 lb. Assume that the modulus of elasticity of the titanium in 16,500,000 psi. If the rod must elongate no further than 0.35 in. when the normal stress of the rod is 68,000 psi, determine the minimum rod diameter AND the maximum rod length.
