Question

In the case of a lever of the third order, the effort arm is always _________ than the load arm.

Answer 1

1. Third-order Lever: In this type of lever, the effort is situated between the load and the fulcrum.
2. In the levers of the third order, the effort arm is always smaller than the load arm.
3. Thus, more effort is required to lift a lighter load.
4. This lever is also called the speed multiplier lever as the load moves through a larger distance than the effort.
5. Sugar tongs, bread knives, fire tongs, etc., are examples of third-order levers.

Hence, in the case of a lever of the third order, the effort arm is always smaller than the load arm.
