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 of95.30kg95.30kgper meter of length, and the tension in the cable was=11650NT=11650N. The crane was rated for a maximum load of500kg500kg.The acceleration due to gravity is=9.810m/s2g=9.810m/s2.
If=5.580md=5.580m,=0.450ms=0.450m,=1.500mx=1.500m, and=1.980mh=1.980m, what was the magnitude ofLWL(the load on the crane) before thecollapse?
L=WL=
NN
What was the magnitude of forcePFPat the attachment pointP?
