Our Forces and Machines Kit engages students in a wide range of physics, physical science, and engineering concepts. Two triple-pulley blocks make it easy to build machines with mechanical advantage up to 6:1. Build all three classes of levers with our pair of 20-cm levers, or combine gears, levers,and pulleys together to show how rotating machines work.

Forces and Machines Basic Kit includes:

  • 27” extruded rails (2)
  • 10 N metal spring scales (2)
  • Extra Tripod Stand base (1)
  • Universal spring hanger
  • Right Angle connector with pulley (2)
