A 15,000 N crane pivots around a friction-free axle at its base and is supported by a cable making a 25° angle with the crane (see figure below). The crane is 16 m long and is not uniform, its center of gravity being 7.0 m from the axle as measured along the crane. The cable is attached 3.0 m from the upper end of the crane. When the crane is raised to 55* above the horizontal holding an 11,000 N pallet of bricks by a 2.2 m, very light cord, find (a) the tension in the cable and (b) the horizontal and vertical components of the force that the axle exerts on the crane. 2.2 m cord Bricks Cable 25 Axle 55 K3,0 m-→
