Equilibrium
Key point
- Net force on a point particle is 0
The equilibrium of a point particle means that the net force on the particle is zero.
The net force on a particle is the one single force whose effect is the same as the combined effect of all individual forces acting on the particle
To solve for the equilibrium you need to
- Find all vector components and add/subtract them as necessary
- If you know Fx and Fy then use the formula on the right
