A uniform horizontal strut weighs 370.0 N. One end of the strut is attached to a hinged support at the wall, and the other end of the strut is attached to a sign that weighs
170.0 N. The strut is also supported by a cable attached between the end of the strut and the wall. Assume that the entire weight of the sign is attached at the very end of
the strut.
