2. A steel (hot-rolled section) column is subjected to axial load P=50KN and a bending moment of 75KN-m on strong axis. The column is 9m long and laterally supported about its weak axis at midheight. The steel is A36 steel with F, = 248MPA. Effective length factor K=1.0. The allowable bending stress on strong axis is 114MPA and the allowable bending stress on weak axis is 85MPA. The properties of the section are as follows: d by 59.5 = 10.5 r; = 150mm d = 345mm S, = 0.00015m A = 5,6000 mm? tw 2t, ry = 47.5mm r = 42.5mm by = 190mm Determine the following: a. Computed axial stress b. Computed bending stress c. The value of the interaction equation. (For the computation of the allowable compressive stress Fa and allowable flexural stress F, apply NSCP 2015).

A cast iron 3m long is completely filled with concrete and used as a vertical strut. If the externaldiameter of the tube is 450mm and the wall is 35mm thick, determine the maximum compressiveload the composite strut can support if the stress in the concrete is not 2N/mm2? By how muchshould the strut shorten under this load? For cast iron EA= 100GN/m2 and for the concrete EB=10GN/m2?
A rectangular steel block is 3.2 inches long in the x-direction, 2.9 inches long in the y-direction, and 4.5 inches long in the z-direction. The block is subjected to a tri-axial loading of three uniformly distributed forces as follows: 48 kips tension in the x-direction, 65 kips compression in the y-direction, and 54 kips tension in the z-direction. If Poisson's ratio is 0.30 and E = 29 x 106 psi, find the uniformly distributed load that must be added in the x-direction to produced no deformation in the z-direction. Your final answer should include two decimal places
