Required information A cast-iron tube is used to support a compressive load of 3 kip. Given: E = 10.5 x 10° psi and that the maximum allowable change in length is 0.025 % and the outer diameter of the tube is 1.8 in, determine, (a) Allowable inner diameter of the tube (b) Is the value a minimum/maximum? Why? The maximum stress in the member is given as Omax (ps)
