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 (Figure 1). 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 the tension in the cable.

2) In the figure below a uniform boom (weight W, = 11,000 N and length L) of a crane is supported by a cable attached of the way from the TOP of the boom. The boom supports & pallet of steel pipes of weight W, = 15,000 N. Here the angle a = 55° and B = 25°. a) Clearly draw all the forces acting on the boom (4 pts). b) Determine the tension in the cable (6 pts) and...
13. A non-uniform beam 4.50 m long and weighing 1.35 kN makes an angle 25o below the horizontal. It is supported by a cable 3.0 m farther down the beam and perpendicular to it. The center of gravity of the beam is 2.0 m down the beam from the pivot. Lightning equipment exerts a 5.00 kN downward force on the lower left end of the beam.

A 25-ft crane supported at its lower end by a pin is elevated by a horizontal cable. A 250-Ib load is suspended through the cable. The center of gravity of the crane is 10 ft from the pin, and the crane weighs 200 lb. Hint: You don't have to convert the unit since they cancel out on both sides. 25. Find the tension in the cable. 26. Find the total force acting on the pin 525016 W(2001)
