Tension and Moments

A 20.0 kg floodlight in a park is supported at the end of a horizontal beam of mass 20.0 kg and length L that is hinged to a pole (beam and pole are perpendicular). A cable at an angle of 30.0 degrees with the beam helps to support the light.
a) Find the tension in the cable.
b) Find the horizontal and vertical forces exerted by the beam on the pole.

Solution Summary

This handwritten solution contains step-by-step calculations to determine tension and horizontal/vertical forces. An annotated diagram is included for further understanding.
