The small crane is mounted along the side of a pickup bed and facilitates the
handling of heavy loads. When the boom elevation angle is q = 40°, the force
in the hydraulic cylinder BC is 7 kN, and this force applied at point C is in the
direction from B to C (the cylinder is in compression). Determine the moment
of this 7 kN force about pivot point O assuming counterclockwise is positive.
