The horizontal axis shows the rotational speed (in rpm) that the crankshaft is turning, and the vertical axis is the torque (in newton-metres) that the engine is capable of providing at that speed. Torque forms part of the basic specification of an engine: the power output of an engine is expressed as its torque multiplied by the angular speed ...
The forces have a turning effect or moment called a torque about an axis which is normal (perpendicular) to the plane of the forces. The SI unit for the torque of the couple is newton metre. If the two forces are F and −F, then the magnitude of the torque is given by the following formula: = where
Torque-free precessions are non-trivial solution for the situation where the torque on the right hand side is zero. When I is not constant in the external reference frame (i.e. the body is moving and its inertia tensor is not constantly diagonal) then I cannot be pulled through the derivative operator acting on L.
In the steady state, the electrical torque is equal to the mechanical torque and hence the accelerating power is zero. [1] During this period the rotor moves at synchronous speed ω s in rad/s. The electric torque T e corresponds to the net air-gap power in the machine and thus accounts for the total output power of the generator plus I 2 R ...
The relationship between and is not intuitive, to the point that many people simply assert that torque and are not related at all. An analogy with a hypothetical linear motor can help to convince that it is true.

When considering torque, the question of using dynamic or static torque for the application is key. For example, if a machine is running at a relatively low rpm (5–50 depending upon size) then dynamic torque is not a consideration since the static torque rating of the coupling will come closest to where the application is running.
