A short rectangular post supports a compressive load of P= 2300 lb as shown. A top view of the post showing the location where load P is applied to the

top of the post is also shown. The cross-sectional dimensions of the post are b = 6.50 in. and d 10.00 in. The load P is applied at offset distances of yp = 2.75 in. and zp =1.50 in. from the centroid of the post. Determine the normal stresses at corners A, B, C, and D of the post.
