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.

Smooth-running ball-bearing clamp pulley for use with inclined planes, force experiments, or demonstrations of work and machines, this durable, lightweight plastic pulley fastens to surfaces up to 18 mm thick.

Economical and effective.

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.

Show the mechanical advantage of the wheel and axle.

These free-running plastic pulleys are durable in design.

This wooden machine is elegantly designed and easy for students to use. Study levers and mechanical advantage both qualitatively and quantitavely.

Investigate the power of simple machines.

Students learn to recognize the difference between work and energy with this apparatus.

An excellent apparatus for showing the function of parts in an AC or DC motor and generator. Operates as either a shunt-wound or series motor. The unit is similar to the St. Louis Motor. Included with the motor are a powerful horseshoe magnet and an electromagnet.
