Torque is a magnitude in physics that expresses the resistance of an object against turning. Its unit is usually Newton-meter (Nm) or pound-foot (lb-ft). It is the result of the multiplication of two basic factors: Force: It is the pulling or pushing applied to an object. It is measured usually in Newton (N). Lift Arm Length: The distance from the point where the force is applied in order to create the turning effect to the turning axis. This distance is usually measured in meters (m). Torque (τ) is calculated as follows: Torque (τ) = Force (F) x Lift Arm Length (L).
