Hollow Circular Post ABC (See Figure) Supports a Load $P _ { 1 } = 16 \mathrm { kN }$

question 3

Multiple Choice

hollow circular post ABC (see figure) supports a load $P _ { 1 } = 16 \mathrm { kN }$ 16 kN acting at the top. A second load $P _ { 2 }$ is uniformly distributed around the cap plate at B. The diameters and thicknesses of the upper and lower parts of the post are $d _ { A B } = 30 \mathrm {~mm} , t _ { A B } = 12 \mathrm {~mm} , d _ { B C} = 60 \mathrm {~mm} , \text { and } t _ { B C } = 9$ 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 $P _ { 2 }$ is Approximately:

• A) \(18 \mathrm { kN }\)
• B) \(22 \mathrm { kN }\)
• C) \(28 \mathrm { kN }\)
• D) \(46 \mathrm { kN }\)
