"Simple Machines"

This package of plastic pulleys contains 25 each of 20, 30 and 40 mm diameter pulleys with 3.2 mm bores and one 10 mm pulley with a push fit to a 2 mm motor shaft.

With the Worm Gear Box, High Efficiency, it is possible to have high power or high speed with two different gear ratios

This balance is the first major advancement in teaching simple machines in decades.

Electric Motor

The High Speed Gear Box, High Efficiency, is perfect for high speed applications

Jumbo-Sized Pulleys are Designed for Classroom Demonstrations

Teach your students about gear ratios and different gear configurations and how these concepts are used to change the amount of applied force to an object.

Identify All Three Classes of Levers and Their Key Parts

Versatile teaching kit contains enough materials for the whole classroom to learn about and experiment with a variety of pulley configurations. Because these activities are hands-on, students get a real feel for the forces at work.
