The discussion revolves around calculating net torque in a physics problem, specifically focusing on the relationship between force, radius, and their vector nature in the context of rotational motion.
The discussion is ongoing, with participants providing guidance on the correct interpretation of the variables involved in the torque calculation. There is an emphasis on understanding the vector nature of the forces and the need for the cross product.
Participants are exploring the definitions and implications of the terms used in the torque formula, indicating a potential misunderstanding of the physical concepts involved.

Not quite.
It is the position vector directed from the centre of rotation to the line of action of the force. Another important point to realize is that you need to take the cross product of F and r, not simply multiply them.dsptl said:then?
