Vectors - Motion and Forces in Two Dimensions - Lesson 3 - Forces in Two Dimensions .... The idea is that the tension, the angle, and the weight are related.


The vertical components of the tensions must equal the weight. (It's in equilibrium .) And the horizontal components add to 0. (It's in equilibrium.).


In physics, tension is the force exerted by a rope, string, cable, or similar object ... held in equilibrium, the tension force must equal the force of gravity on the weight . ....
