3.) A 15000-N crane pivots around a friction-free axle ats its base and is supported by a cable making a 25° angle with the crane shown in the figure. 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. (a) When the crane is raised to 55° above the horizontal holding an 11000-N pallet of bricks by a 2.2-m very light cord, find the tension in the cable. (b) Find the horizontal component of the force that the axle exerts on the crane. (c) Find the vertical component of the force that the axle exerts on the crane.
