In static equilibrium, both the net force and net torque on a body add up to zero.

The conditions for static equilibrium of an extended object are that the net force is

∑

F

y

=0

and

∑

F

x

=0

and the net torque by

∑τ=0

.

In this Demonstration you can vary the forces and moment arm for either forces applied to the object and watch the effect these forces have on the object.
