Unless noted otherwise, neglect the weights of the members in these problem.

With reference to Problem, calculate the eccentricity that must exist if the combined stress at outer edge AA is to be zero.

Problem

A short compression member is subjected to a compressive load of 300,000 lb at an eccentricity of 1.5 in., as shown. The member is 12 in. by 12 in. in cross section. Calculate the combined stresses at the outer edges AA and BB.
