The discussion focuses on calculating net torque using the formula Tnet = F x r, where F represents the force and r is the position vector from the center of rotation to the line of action of the force. Participants clarify that the calculation requires the cross product of the force and the radius, rather than simple multiplication. The correct approach emphasizes understanding the vector nature of torque, which is crucial for accurate calculations in physics problems.

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?
