Actually, there are two forces at work; Normal and Shear. Normal is the feet pressing downward and perpendicular while transferring weight and shear is parallel with the rotational movement of the hips.
Torque is created by Shear forces moving rotationally and creating clubhead speed against and with a solid base of normal force going into the ground.
I didn't read this post the first time but this is partly incorrect also. Normal force would be the ground pushing up on the feet. What you are describing is called normal stress. This info doesn't really have much relevance to this thread anyways though. Physics terms probably should be left out of golf instruction.
