CPM Homework Help : PC3 Problem 10-100

A large picture weighing 40 pounds is being suspended as shown in the diagram at right. How much tension is on one side of the cable?

Hint:

The sum of the vectors in the diagram must be $0$ since the picture is not moving.
Use this information to solve for F, the force that is distributed into the cable vectors.

3 rays, with common endpoint, downward ray labeled as vector, 0, comma negative 40, north west ray labeled as vector, negative 2.5, F, comma 1 F, north east ray labeled as vector, 2.5, F, comma 1 F.
