A hollow circular post ABC (see figure) supports a load Pt= 1700 lb acting a1 the top. A second load P2 is uniformly distributed around the cap plate at B. The diameters and thicknesses of the upper and lower parts of the post are AB = 1.25 in.,t AB = 0.5 in., dBc= 2.25 in_ and tBC= 0.575 in., respectively.

(a) Calculate the normal stress aAB in the upper part of the post.

(b) Ifyou want the lower part of the post to have the same compressive stress as the upper part, what should be the required magnitude ofload P2?

(c) If P1 remains at 1700 lb and P2 is set at 2260 lb, what new thickness of BC will result in the same compressive stress in both parts?
