Homework Help: physics

Posted by Seth on Friday, April 1, 2011 at 3:10pm.

"A 1220-N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. A 1960-N crate hangs from the far end of the beam. Find a) the magnitude of the tension in the cable and b) the magnitude of the horizontal and vertical components of the force that the wall exerts on the left end of the beam. (The cable makes an angle of 50 degrees with respect to the horizontal and the beam makes an angle of 30 degrees.)"

According to my textbook, the answers are a)2260N and b) 1450N for both the horizontal and vertical components. I just really need some help in setting up this problem to get those answers.
