Claim: Two arm wrestlers can end up in a tie.

Evidence: This occurs when both wrestlers exert equal force against each other. We can observe this visually during a match where neither wrestler's arm moves despite significant effort. Measurements of force applied by each wrestler using a force gauge attached to their wrists would show near-identical readings during a tied match. Video analysis could also be used to track the movement (or lack thereof) of each wrestler's arm, providing quantitative data supporting the claim. Furthermore, the lack of movement indicates a balance of forces.

Reasoning: This outcome is consistent with Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. In the context of arm wrestling, the action is the force exerted by one wrestler on the other's hand. The equal and opposite reaction is the force exerted by the second wrestler back onto the first. When these forces are equal in magnitude and opposite in direction, the net force is zero, resulting in no movement and a tie. The forces are balanced, preventing either wrestler from overpowering the other. Any slight imbalance in force, however small, would result in one wrestler winning. The tie demonstrates a precise equilibrium of opposing forces. The absence of acceleration in either direction further supports the conclusion that the forces are equal and opposite. Therefore, the observed tie directly supports Newton's Third Law.
