A simply supported beam is subjected to the end couples (bending is about the strong axis) and the axial load shown in the figure
below. These moments and axial load are from service loads and consist of equal parts dead load and live load. Lateral support is
provided only at the ends. Neglect the weight of the beam and investigate this member as a beam-column. Use Fy
that P40 k and M = 68 ft-k.
