Equilibrium is the condition of a system in which all competing influences are balanced. These can range from forces (static/dynamic equilibrium), to chemical processes (chemical equilibrium) and temperature gradients (thermal equilibrium).

Evaluating sum of torques for different choices of origin when solving equilibrium problem
The friction force is proportional to the normal force, which depends on both gravity and the applied force. Letting the friction force $F_s$ stand on its own, the correct expression for the torque ab …

Evaluating sum of torques for different choices of origin when solving equilibrium problem
My textbook says,
When applying equilibrium conditions for a rigid body, we are free to choose any point as the origin of the reference frame. … (source)
I am trying to understand this by looking at the following picture (from an exercise problem), in which the ball is in static equilibrium because of the applied horizontal force $\vec F$ and …
