P₁ P2 TAB dAB B dBC TBC A hollow circular post ABC above supports a load P1=1700 N 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 pars s of the posts are dAB=12.5mm, tAB= 5mm, dBc=22.5mm, and tgc=3.75mm, respectively. If it is desired that the lower part of the post have the same compressive stress as the upper part, what should be the magnitude of the load P2? P2= N B A TAB dAB -dBC TBC A hollow circular post ABC above supports a load P1=1700 N 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 pars of the posts are dдB=12.5mm, tAB= 5mm, dBc=22.5mm, and tBc=3.75mm, respectively. Calculate the normal stress in the upper par of the post. σ AB= N/mm²
