2D Rigid Body Rotational Kinetics Torque: τ (1) Torque is the rotational effect of the force, indicating the tendency of the force to turn a body. In engineering it is also called moment. sin t FF r F r τ φ =⋅=⋅ =⋅ A is the lever arm (or moment arm) defined as the perpendicular distance from the pivot to the line of action of the force vector r is the distance from the pivot to the point of application of the force is the angle between F and r (2) Torque is a vector with magnitude and direction, and the vector definition of torque is
