A24’ long w8 x 35 steel column is used to support an axial load. the column is made of astm a992 structural steel with and elastic modulus of 29,000 ksi and a yield strength of 50 ksi. it is pinned at both the top and bottom and the cross-sectional area is 10.3 in2 . the moment of inertia about the strong axis is 127 in4 and about the weak axis is 42.6 in 4 . calculate the maximum allowable load (in kips) on the compressive member considering buckling and yielding (by considering fos=1.5). [abs. to check: pallor = 98kupd)
