torque definition?

Answer 1

In physics, torque can informally be thought of as "rotational force". The SI units for Torque are newton metres although centinewton meters (cN·m), foot-pounds force (ft·lbf), inch pounds (lbf·in) and inch ounces (ozf·in) are also frequently used expressions of torque. The symbol for torque is τ, the Greek letter tau. The concept of torque, also called moment or couple, originated with the work of Archimedes on levers. The rotational analogues of force, mass, and acceleration are torque, moment of inertia, and angular acceleration respectively. The force applied to a lever, multiplied by its distance from the lever's fulcrum, is the torque. For example, a force of three newtons applied two metres from the fulcrum exerts the same torque as one newton applied six metres from the fulcrum. This assumes the force is in a direction at right angles to the straight lever.

More accurately, torque on a particle (which has the position r in some reference frame) is defined as the cross product:

Answer 2

Torque=Force X Distance at which the force is applied.

Its unit: N-m

If you nail a rod and apply 1 Newton force at a distance of 1 metre from the nail, it amounts to your applying 1 N-m torque about the nail.
