Simple Machines – Pulley

The pulley is one of the basic simple machines and can be found everywhere around us. They are used in cranes, to lift heavy weights. Or when you hoist a flag.

It provides mechanical advantage, making it easier to move heavy masses. But how exactly does it work? Find out this and more by experimenting with this Pulleys Model. This wooden model is ideal for classroom demonstrations.

This apparatus can model how the use of several pulleys increases mechanical advantage. Students can use this both qualitatively and quantitatively. The design of this pulley lends itself easily to inquiry based activities. What happens if you change the weight at the end of the pulley? And do you have to apply more or less force if you use 2 pulleys? And what if you use 3 pulleys? What happens to the direction and the magnitude of the force applied? Can you come up with an everyday situation where you can use a pulley? There is so much to discover! This model includes an instruction manual to facilitate both student and teacher with the use of this model. The model is made of particle board and MDF components. The sturdy construction of the models makes it perfect for classroom use. The base of the model measures 16.5 cm (L) x 8.9 cm (W) x 41 cm (H).
