1. Content:
Exhibition items are designed with two sets of axles, each with two wheels of varying sizes, with the larger one having a diameter twice that of the smaller one. Adults and children can participate simultaneously. Two people stand next to the two wheels of the exhibition items, each rotating a wheel in different directions, trying to see who can twist over whom. When the visitor is on one side of a larger wheel, they use less force to rotate the wheel, but the other party must use a lot of force to counteract it.
2. Principle:
In lever motion, the larger the ratio of the force arm to the resistance arm, the more effortless it is. People who turn the big wheel easily defeat those who turn the small wheel. This is because the effect of object rotation is not only related to the magnitude of the force, but also to the point of application and direction of the force. In fact, this device is a deformed lever - a wheel axle, which can change the force arm of torque, thereby achieving the change of torque magnitude. During the rotation process, the force arm of the large handwheel is twice that of the small handwheel, so rotating the large handwheel will be more effortless than the small handwheel.
3. Purpose:
By having children and their parents rotate in opposite directions to each other in a wrestling game, they can experience the principles of leverage and torque.
