A hollow circular post ABC (see figure) supports a load P1 = 16 kN acting at 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 dAB = 30 mm, tAB = 12 mm, dBC = 60 mm, and tBC = 9 mm, respectively. The lower part of the post must have the same compressive stress as the upper part. The required magnitude of the load P2 is approximately:
(A) 18 kN
(B) 22 kN
(C) 28 kN
(D) 46 kN
