(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A uniform beam of length 1.0m and mass 10 kg is attached to a wall by a cable (the cable makes a 30 degree angle with the beam). The beam is free to pivot at the point where it attaches to the wall. What is the tension in the cable?

2. Relevant equations

F(net) = F(beam) - F(cable) = 0

torque = [F(beam) x d(beam)]+[F(cable) x d(cable)]

3. The attempt at a solution

I think these equations are correct. I was able to figure out the torque of the beam (10kg x 9.8m/s2 x 1.0m) but I am having trouble figuring out what to do with the cable. How and where do I use the angle? Do I use it to find the distance of the cable itself? or its distance up the wall?
