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 kg93.60 kg per meter of length, and the tension in the cable was ?=12690 NT=12690 N. The crane was rated for a maximum load of 500 kg500 kg. If ?=5.000 md=5.000 m, ?=0.558 ms=0.558 m, ?=1.050 mx=1.050 m, and ℎ=2.250 mh=2.250 m, what was the magnitude of ?LWL (the load on the crane) before the collapse? The acceleration due to gravity is ?=9.810 m/s2g=9.810 m/s2.

?L=? N

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

?P= ? N
