Question

What should be the total vertical force in system when body is in equilibrium?

Answer 1

1. When the body is in equilibrium, the net force acting on it in all directions is zero (that is, the forces in the Y direction balance themselves).
2. Thus, we can say that if we add all forces together as vectors, the force will be $0Newton$.
3. So, in other words, the sum of all forces acting on it must be zero for a body to be in equilibrium.
