Three forces acting at a point are in equilibrium. The forces are 930 lb, 760 lb, and 1220 lb. Find the angles between the directions of the forces. (Hint: Arrange the forces to form the sides of a triangle.)
We can use Cosine Theorem to solve this problem:
The three forces form the sides of a triangle: pls refer to the ...
Trigonometry is used to solve for angles between forces.
