A hollow circular, gray cast-iron pipe supports a red brass rod and weight W = 2 kips, as shown. The outside diameter of the pipe is d = 6". If the allowable compressive stress in the pipe is 5000 psi and the allowable shortening of the pipe is 0.02", what is the minimum required thickness t?(Include the weights of the roits own weight?d and the A-36 stee cap in your calculations.) What is the elongation of the brass rod due to both load W and its own weight? What is the minimum required clearance h?
