- Torque is the turning effect of a force applied at a perpendicular distance from the centre of rotation of a rotating object.
- A torque (also spelled torc) is a necklace that consists of a narrow, twisted band made of metal.
- Torque is the force that affects rotational motion; the greater the torque, the greater the change in this motion.
- A torque is distinguished from a force because it does not change the velocity of the satellite, only its attitude (or angular momentum).
- Torque is the time- derivative of angular momentum, just as force is the time derivative of linear momentum.
- The "power" of the power stroke is what creates torque, so we all want to maximize the pressure pushing on the piston in order to maximise torque.
- The rotation of the piston 8 causes corresponding rotation of the shaft 10 about the axis 14 and thereby imparts torque to the shaft 10.
