Question

Enunciate two principles of equilibrium?

Answer 1

Explanation:

1)Two force principle: States that if two forces are in equilibrium they must be equal, opposite and collinear. 2)Three force principle: States that if three forces are in equilibrium then resultant of any twoforces must be equal, opposite and collinear with the third force.

Answer 2

1) if two forces are in equilibrium they must be equal, opposite and collinear.

2) if three forces are in equilibrium then resultant of any twoforces must be equal, opposite and collinear with the third force
