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

A 12-in.-square concrete pedestal is subjected to a 100-kip vertical eccentric load applied on the Y–Y axis, as shown. Determine the required magnitude of the horizontal load P (also in the vertical plane through the Y–Y axis) for a combined stress of zero at point A.
