... Magnitude of torque is defined as the product of the force exerted on the object to rotate it and the moment arm. When there are more than one force being exerted on certain points of the object, one can sum up the torque generated by each force vectorially. The convention for sign of the torque is ...

... Team A exerts a tension of 200 N on the rope. Thus, FA on rope = 200 N. Similarly, FB on rope = 200 N. But the two tensions are an interaction pair, so they are equal and opposite. Thus, the tension in the rope equals the force with which each team pulls (i.e. 200 N). According to Newton’s third law ...
