Do experiment- Make a DIY Moving Hoist
1. Non-toxic wooden and plastic materials.
2. Block and tackle is a system of two or more pulleys with a rope or cable threaded between them,
usually used to lift or pull heavy loads. The pulleys are assembled together to form blocks and then
blocks are paired
so that one is fixed and one moves with the load. The rope is threaded, or wove, through the pulleys
to provide mechanical advantage that amplifies the force applied to the rope.
3. A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which
rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use
chain, fiber or wire rope as its lifting medium.
