Torque is the turning effect of the force about the axis of rotation. The moment of force is called Torque. It is Rotational analogous of Force. . Torque is a turn or twist force acting. Lets have a simply illustration to know that. When we apply the force the door turns on it is hinges. Thus a turning effect is produced when we try to open the door. Have you ever tried to do therefore by applying the force near the hinge? In the first case, we’re able to open the door with ease. In the second case, we have to apply much more force to cause the same turning effect. What’s the reason?. This turning effect produced by a force on a rigid body about a point, pivot or fulcrum is called the moment of a force or Torque . .
