PRO BLEM 2: A TRICKY STRUT An orange strut of length l is connected to a wall via a pi vot at the bottom. An additional (blue rope) also connec ts the strut to the wall attached at an angle 01. A load of weight W is hanging from the strut; the load makes an angle 02 with the strut as shown in the diagram. In order to stabilize the system, and additional force needs to be applied. That force, which is labeled C in the diagram, makes an angle p with respect to the strut as shown. What is o?
