Design a jib crane as shown in Figure P5-60 that will support a downward load of 6000 lb. Choose a common structural steel shape for all members. Use allowable stresses of 0.66Sy (Sy is the yield strength of the material) in bending, and 0.60Sy in tension on gross areas. The maximum deflection should not exceed 1/360 of the length of the horizontal beam. Buckling should be checked using Euler's or Johnson's method as applicable.
