Question

Two cables suspend a 500 N sign above the hallway. The left cable makes a 40 degree angle with the ceiling and the right cable makes a 50 degree angle with the ceiling. What is the tension in the left and right cables?

Answer 1

The tension is such that it holds the signs up, and the cable is in equilibrium.

first of all, the weight:

500=T*sin40+T*sin50

solve for T
