Torque Torque Torque, moment, or moment of force is the rotational equivalent of linear force. The concept originated with the studies of Archimedes on the usage of levers. Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object. The symbol for torque is typically formula_1, the lowercase Greek letter "tau". When being referred to as moment of force, it is commonly denoted by "M". In three dimensions, the torque is a pseudovector; for point particles, it is given by the cross product of the position vector (distance vector)
Torque to a vector, whereas for energy, it is assigned to a scalar. A conversion factor may be necessary when using different units of power or torque. For example, if rotational speed (revolutions per time) is used in place of angular speed (radians per time), we multiply by a factor of 2 radians per revolution. In the following formulas, "P" is power, "τ" is torque, and "ν" (Greek letter nu) is rotational speed. Showing units: Dividing by 60 seconds per minute gives us the following. where rotational speed is in revolutions per minute (rpm). Some people (e.g., American automotive engineers) use
