This Demonstration shows how to find the torque, or moment of force, exerted by a rope on a boom about the point . The torque is a vector quantity, usually written . You can vary the force and the distance . When distance is expressed in meters (m) and force in newtons (N), the torque or moment has the dimension newton-meters (Nm).
