Bumper Class Pulleys Pack

An essential for D&T classrooms, this bumper pack of plastic pulleys includes a variety of different sizes ranging from 10 to 50mm.

  • The pulleys have either a 2mm or 4mm centre hole and fit on to the included steel axles.

  • The steel axles provide a central rod around which the pulley rotates and help to distribute the load, ensuring the weight or force applied to the pulley is evenly supported.

  • Use to demonstrate to children how pulleys are a simple mechanism that make lifting and moving things much easier and that pulleys allow a smaller force, to have a greater effect.

  • Explore how the size of a pulley can have an impact on how the pulley system functions, investigating whether larger pulleys can affect the speed and distance travelled by the load.

  • The pulleys are also a useful addition to Science investigations on forces and motion.
