...cable at the other end.? A 1235-N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. A W = 1885-N crate hangs from the far end of the beam.
(a) Using the data shown in the drawing, find the magnitude of the tension in the wire.
(b) Using the data shown in the drawing, find the magnitude of the horizontal and vertical components of the force that the wall exerts on the left end of the beam.

How should I approach the problem? The length of the beam is unknown, but there must be a way to calculate the torque of the block and the torque of the beam (center of mass at midline), which should then be equal in magnitude to the torque of the wire, so that the net torque is 0 and the beam is at rest.
