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

A uniform, horizontal beam of length 4 weighs 150 N. It is connected to a wall by a hinge and is held horizontal by a cable of length 5; it holds a 300 N weight at its end away from the wall. The cable and the beam form a 3:4:5 triangle with the wall.

2. Relevant equations

[tex]\sum_{i=1}^n\textbf{F}_i=m\textbf{a}_i=0[/tex], because the system is not accelerating.

3. The attempt at a solution

The forces acting upon the end of the rod are half of its weight, the hanging weight, and the tension. I've solved for [tex]textbf{T}[\tex] to no avail. What am I doing incorrectly?
