What does pulley mean and explain its working.

The simple machines can be divided into six main components that are: pulleys, levers, screws, wheels as we will as axles, inclined planes, as well as wedges. The inclined planes Wedge, as well as screws, come in the category of the inclined plane while pulleys as we will as wheels are a type of lever. Here we discuss all the pulley. This is wheel-shaped containing grooved rim. It is mainly used for the reduction of force. If we want to hoist up a heavy load then we will have to exert force on the downside of the rope. So, it is easy to move down a load rather than taking it on the upside with the use of a rope which needs a greater force than the former condition. In all these processes, the movable pulley is used which is attached to the load as we will as reduce the level of required force to do the work. The combination of the pulley is used to alter the amount of required force as well as the direction of work. Thus, it is useful for moving, pulling, lifting loads and also makes our heavy work easier.

Working

We pull the rope down to lift the weight up. If you want to lift something that weighs 100 kg, you have to pull down with a force equivalent to 100 kg, which is 1000N (newtons). If you want to raise the weight 1 m into the air, you have to pull the loose end of the rope a total distance of 1 m at the other end.
