Torque is a measure of how much a force acting on an object causes that object to rotate. 
Mathematically, Torque is defined as

 = r x F = r F sin()

In other words, torque is the cross product between the distance vector (the distance from the pivot point to the point where force is applied) and the force vector, '' being the angle between r and F.
Using the right hand rule, we can find the direction of the torque vector. If we put our fingers in the direction of r, and curl them to the direction of F, then the thumb points in the direction of the torque vector.
