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 Σ"τ" = 0. That is, to solve statically determinate equilibrium problems in two-dimensions, three equations are used. When the net force on the system is zero, the torque measured from any point in space is the same. For example, the torque on a current-carrying loop in a uniform magnetic field is the same regardless of your point of reference. If the net force formula_26 is not zero, and formula_27 is the torque measured from formula_28, then the torque measured from formula_29 is … formula_30 Torque is part of the basic specification of an engine: the power output of an engine
