I am unsure of how to go about this problem, because whatever I tried wasn't right. So if anyone could help me by going step by step through it, showing all equations and numbers used, and then showing me the answers so I can make sure I get the same thing, I would appreciate it.
A uniform beam of length x = 1.0 m and mass 10 kg is attached to a wall by a cable at angle Θ = 30° to the horizontal, as shown in the figure. The beam is free to pivot at the point where it attaches to the wall. What is the tension in the cable?
