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

Rework Problem, but assume that the applied load is 150,000 lb instead of 40,000 lb.

Problem

A concrete pedestal is in the shape of a cube and is 6 ft on each side. The pedestal supports a superimposed load of 40,000 lb located on the Y–Y axis, as shown. Calculate the maximum eccentricity e for zero tension at the base of the pedestal. Include the weight of the pedestal using a concrete unit weight of 150 pcf.
