B Arm-wrestling -- question about forces

  1. Jan 2, 2018 #1
    In the arm-wrestling, when the hand A prevails on the hand B, the force of A on B is greater than that of B on A?

    No. That would violate Newton's third law. The torque on the arm of B from the force from A is greater than the torque on the arm of B that B is able to generate.

    OK thanks.

    Therefore the force exerted by the hand A (also of the strongest man in the world) on the hand B, can never exceed (not even a little) the strength that the hand B exerts on the hand A (therefore represents its maximum limit).

    “Strength” is not a standard physics concept. Do not confuse it with force, which is.
