A mechanic hangs a sign outside the workshop as shown below. The 200.0-N sign hangs from
a beam that weighs 50.0 N. The beam is attached to a wall by a hinge, and the other end of the
beam is supported by a cable whose breaking strength is 417 N. The beam is 1.50-m long.
The sign’s dimensions are 1.00 m horizontal and 0.80 m vertical.
(a) Sketch a free-body diagram for the beam.
(b) Determine the minimum angle θ that can exist between the beam and the cable.
