7-Piece Pulley Set for School Technology Projects

Seven pulley wheels in different sizes and a drive belt. Run the belt from a small wheel to a large one and the output turns slower with more force. Reverse it and you get speed instead. That trade-off is most of what the mechanisms section asks a learner to demonstrate.

What is in the pack

• Seven pulley wheels in graded diameters
• Drive belt

Covers Mechanical Systems and Control in CAPS Technology, Grades 7 to 9. Useful as a spares pack too, since pulleys are the part most likely to go missing from a half-built project.
