A concrete pier 20 in. X 24 in. supports a load of 100 kip at point E as shown. Determine the stresses at the four corners of the pier and locate the neutral axis if point E is located at (a) distances e, = 0 and e₂4 in., and (b) distances e, 6 in. and e₂ = 4 in. from the axes of symmetry for the cross section. (Hint: The neutral axis can be found by locating points of zero stress on two sides of the pier.)
