Principle
- The students should measure the forces which maintain equilibrium with different load masses on a step wheel.
- They should measure the force and the length of the load arms of a step wheel, and calculate the products load × load arm and force × force arm.
From their measuring results they should conclude that, under static conditions, a step wheel works like a lever and that the aforementioned products should be equal - as it is the case for a lever.
Benefits
- Student-suitable experiment descriptions with reports available
