A 1290-N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. A W = 1805-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.
