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.

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.

Identify All Three Classes of Levers and Their Key Parts

Students explore conservation of momentum with real-world machinery in this Collision Cart.

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.

With custom designed components, this kit covers all the subject areas two or three individual kits usually address.
