A sign weighing 500N is suspended at the end of a uniform 300N beam 5m in length, as shown. The beam is attatched to the wall with a hinge, and its other end is supported by a wire. What is the tension in the wire if it makes an an angle of 30o with the beam?

Help please. Use the correct equation and then plug the numbers into that equation
Answered by bobpursley
sum moments about the hinge: assume the cg of the beam is at the center.
clockwise moments are positive.
5/2 *300-T*sin30*5+500*5=0
solve for Tension T
