There are always forces acting on an object, but all of these forces, when added together must equal zero. We call this state ‘equilibrium’. Equilibrium: Sum of Forces in the x-direction = 0 Su ...

For example, when one of the chosen coordinates is an angle, the corresponding E-L equation can be interpreted as a statement of balance of torque. In this case, the force conjugate to the angular coordinate is a torqu ...
