5. a) Determine the maximum axial load the member shown can support before you would expect it to yield. The structure is made of A36 steel. The thickness of the structure is 2.0 in., the larger width is 12.0 in., and the smaller width is 8.0in. The fillet radius is 0.5in. b) A 35 ksi axial stress is applied to the beam cyclically (repeatedly applied then removed). How many times can this be done before you would expect the part...
