The beam supports the load of P = 5.7 kip. As a result, the A-36 steel member BC is subjected to a compressive load. Due to the forked ends on the member, consider the supports at B and C to act as pins for x?x axis buckling and as fixed supports for y?y axis buckling. Part A Determine the factor of safety with respect to buckling about the x?x axis. Part B Determine the factor of safety with respect to buckling about the y?y axis.
