Question
A $$20.0-kg$$ flooding in a park is supported at the end of horizontal beam of negligible mass that is hinged to a pole as shown in Figure $$12.18$$. A cable at an angle of $$\theta =30.0^o$$ with the beam helps support the light.
Draw a force diagram for the beam. By computing torques about an axis at the hinge at the left hand end of the beam, find
