A 21.0-kg floodlight in a park is supported at the end of a horizontal beam of negligible mass that is hinged to a pole as shown in

the figure below. A cable at an angle of 8 = 32.00 with the beam helps support the light.

(a) Draw a force diagram for the beam. Choose File no file selected

This answer has not been graded yet.

(b) By computing torques about an axis at the hinge at the left-hand end of the beam, find the tension in the cable.

(c) Find the horizontal component of the force exerted by the pole on the beam.

Now solve the same problem from the force diagram from part (a) by computing torques around the junction between the cable

and the beam at the right-hand end of the beam.

(e) Find the vertical component of the force exerted by the pole on the beam.
