Hydraulic torque wrenches are used for tightening large torques with high accuracy. The sum of these forces and torques yields the resultant force-torque. The yaw torques must be resolved by roll and pitch transformations. They exert forces on nearby moving electrical charges and torques on nearby magnets. I disk migration driven by torques arising from Lindblad and co-rotation resonances. The common method to deal with gravitational torques is a field theory. Forces that cause extended objects to rotate are associated with torques. The same applied magnetic field creates larger torques on objects with larger magnetic moments. These rotations are produced by torques (or moments) about the principal axes. The input axis is the axis about which input torques are applied. This gives rise to an imbalance in torques that starts the precession. The opposite torques from the rotors cancel each other out. Illyrian rulers wore bronze torques around their necks. Output torques have the reverse sign of input torques. For all three, these are the torques applied to the mechanism (input torques).
