Question

After an unfortunate accident occurred at a local warehouse, you were contracted to determine the cause. A jib crane collapsed and injured a worker. An image of this type of crane is shown in the figure.The horizontal steel beam had a mass of 93.60 kg per meter of length, and the tension in the cable was ?=12690 N . The crane was rated for a maximum load of 500 kg . If ?=5.000 m , ?=0.558 m , ?=1.050 m , and ℎ=2.250 m , what was the magnitude of ?L (the load on the crane) before the collapse? The acceleration due to gravity is ?=9.810 m/s2 .

WL=?

What was the magnitude of force ?PFP at the attachment point P?

FP=?
