Rework given 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.
