A 49 in long simply supported hollow circular steel tube has a 1.68 in OD and 0.392 in wall thickness. The cross-section is shown below. Use an allowable bending stress of 1.022 kpsi for steel and find the maximum safe uniformly distributed load that the beam can carry, if the loading is in the direction. Maximum safe uniformly distributed load- lbf/in.
