Physics - 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
This will be true regardless of the point around which you take
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.
