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 85.10 kg per meter
of length, and the tension in the cable was T = 11650 N. The
crane was rated for a maximum load of 500 kg. The
acceleration due to gravity is g = 9.810 m/s².
If d = 5.290 m, s = 0.558 m, x = 1.200 m, and h = 1.890 m,
what was the magnitude of $W_L$ (the load on the crane) before
the collapse?
What was the magnitude of force $F_P$ at the attachment
point P?
$W_L$ =
N
$F_P$ =
