The Weakling's Victory (Test of Strength)
★Exhibit Content: Lever Principle ★Interaction: Mechanical Interaction ★Operation: Both participants adjust the height position of the rope, grab the rope and engage in a tug-of-war. ★Exhibit Description: The exhibit consists of a pointer model, rope, scale, etc. Both participants each grab the ropes on either side for a tug-of-war. Try adjusting the height position of the rope multiple times to explore the principle of the lever. ★Scientific Principle: If the two teams are evenly matched in strength, the team with the longer lever arm will win, demonstrating the lever principle. Wouldn't you be happy if you won a tug-of-war against someone much stronger than you? The 'Victory of the Weak' device can make such a wish come true. Just adjust the height of the rope, then pull the higher rope to easily defeat your opponent. This is because, according to the lever principle, to balance a lever, the two torques acting on the lever must be equal in magnitude. Therefore, if you pull the rope at a higher position, that is, the side with the longer lever arm, you can easily win against the side pulling the rope at a lower position (with a shorter lever arm). When experiencing it, everyone can verify whether this situation occurs.
