Simple machines can be used to gain force, gain path, change the direction of force, change the rate at which work is done, or convert one form of energy into another. Reels: One of the simple machines that provides ease of doing business is the reel. There are 3 types of reels. Fixed rollers: Moving rollers pulleys Fixed reel: On fixed reels, only the reel spins. They are reels used as mounted on a place. In use, it has the ability to change the direction of the force. These reels do not gain strength. A force equal to the load is used to lift the load. To lift a load of 50 N, it is necessary to pull the end of the rope by 50 N. Movable reel In moving pulleys, the load is connected to the free pulley. The formula is "Force = Load/number of rollers". Pulley Main article: Palanga The pulley is a combination of pulleys used to lift a lot of load with less force. It occurs by adding one or more movable pulleys connected to the same body to the fixed pulley. In these systems, the force to be applied can be reduced by dividing the force and transferring a part of the load to the fixed pulleys. The force to lift the load on pulleys is calculated by dividing the weight of the load by the number of pulleys. The strength gain in pulleys is equal to the number of ropes acting on the moving pulleys. While calculating the force to be applied on the pulleys, the weights of the moving pulleys are also taken into account. There is gain in strength in pulleys.
