A boom of mass m supports a steel girder of weight W hanging from its end (see figure below). One end of the boom is hinged at the floor; a cable attached to the other end of the boom and pulls horizontally on it. The boom makes an angle (theta) with the horizontal.
For (theta) = 0, does T approach zero or infinity?
For (theta) = 90, does T approach one or zero?
