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.
