A box of mass M=500 kilogram hangs by a rope from a beam with dimensions a=2.0 meter and b=3.0 meter. The beam has mass m=85 kilogram. Determine the tension Tc in the cable and find the magnitude of the net force F exerted on the beam by the hinge. (Engineering firms typically require calculating this to ensure that the beam is strong enough for certain load).
