Calculating Torque With Examples ThoughtCo

Oct 18, 2018· In calculations, torque is represented by the Greek letter tau: τ. Torque is a vector quantity, meaning it has both a direction and a magnitude. This is honestly one of the trickiest parts of working with torque because it is calculated using a vector product, which means you have to apply the right-hand rule.
