Pulley Demonstration Model
Product Code : SCL-PLE-11954
Quick Answer: The Pulley Demonstration Model is a school physics model with fixed and movable pulleys on a metal frame, used to show how pulleys change the direction of a force and reduce the effort needed to lift a load.
Last updated: 18 October 2026
Key Features
- Fixed and movable pulley arrangements on one model.
- Metal frame with plastic pulleys and a nylon rope.
- Load hooks for hanging the load to be lifted.
- Lets the effort needed with different pulley arrangements be compared directly.
Technical Specifications
| Specification | Value |
|---|---|
| Frame | Metal |
| Pulleys | Plastic, fixed and movable |
| Rope | Nylon |
| Components | Fixed pulley, movable pulley, rope, load hooks |
| Level | School, primary to secondary |
How It Is Used
The model is stood on a firm surface, a load is hung on the hook and the rope is pulled to raise it, first over the fixed pulley and then with the movable pulley. Measuring the effort and the load each time lets students calculate the mechanical advantage and see how each arrangement changes the force needed and its direction.
Frequently Asked Questions
What types of pulley are on the Pulley Demonstration Model?
A fixed pulley and a movable pulley, with a nylon rope and load hooks, so the two arrangements can be compared.
What can students work out with the Pulley Demonstration Model?
By measuring the effort applied and the load lifted, they can calculate the mechanical advantage of each pulley arrangement.
