How torque is produced in a induction motor?

Torque is a Force applied at a Moment Arm. Or a force applied to a bar of a set length. Torque is a unit of Foot-pounds. If you have a ratchet wrench that has a 1 foot handle and you use it to torque a Bolt by applying a force of 20 lbs this will produce a 20 ft-lb torque load to the bolt. ( 1 Foot X 20 Lbs). This can be converted to 240 inch-lbs. The torque produced by car engines are also measured in terms of foot-pound of torque. This defines the power that the engine produces at the Shaft. This is convenient to use in calculating how much power is delivered to a car's transmission or wheels to allow the engineer to determine how fast the car will go, etc.
