Hi, Let us assume that I apply some amount of force at the end of the wrench to loosen a nut. This force makes the wrench to rotate in clockwise direction. So the direction of the torque should also be in clockwise direction. However, we usually use the definition of cross product to determine the direction of Torque ie if both position vector and Force vector are in the xy plane then the direction of Torque will be either +ve z-axis or -ve axis depending upon the rotation of the body. My confusion is why can't we say the direction of the torque is in clockwise direction or counter clockwise direction?? What exactly it means if we say the direction of the torque is along +ve z axis or -ve z axis??
