Physics - Static equilibrium

Static equilibrium

If a structure is not accelerating or rotating then it is in static
equilibrium. This means it is in both translational and rotational
equilibrium. [1]

This will be true regardless of the point around which you take
torques/moments.

The fact that a structure is in static equilibrium can be used to
determine the forces that are acting on it. You need to analyse a structure
in terms of torques, or forces or both.

When you do need to use torques, you will have to choose a point around
which to calculate ('take') torques. Choose a point which will allow you to
temporarily eliminate one of the unknown forces to simplify the problem.
