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.

Question
4. 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 11,000N 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.
