Investigate the power of simple machines.

• Instructions Included
• Four Interchangeable Wheels
• Students See Relationship between Wheel Size and Mechanical Energy Produced

A large-scale wheel and axle demonstrate the mechanical advantages and real-world uses for this basic yet indispensable device. From everyday functions in automobiles, fishing rods, and door knobs to more advanced concepts like the Atwood machine, students investigate the many ways that this machine is used to efficiently increase force and distance.

Four interchangeable wheels are included with diameters of 1 cm, 10 cm, 20 cm, and 30 cm, allowing students to see the direct relationship between wheel size and mechanical energy produced.
