1. Lever - A lever is a simple machine that requires a pivot point or fulcrum and uses a force or effort to move an object. They are used to lift, move, and balance objects. Examples of uses for a lever include a crowbar for prying open a container, a seesaw for entertainment, and scissors for cutting.
2. Pulley - A pulley is a simple machine that consists of a wheel with a rope or cable wrapped around it. Pulleys are used to lift heavy objects or move them from one place to another with less effort. Examples of uses for a pulley include a flagpole to raise and lower a flag, a crane used in construction to lift building materials, and lifting weights in a gym.
3. Wheel and Axle - A wheel and axle consist of a wheel attached to an axle. It uses rotational motion to move objects. They are used in various machines, including vehicles, bicycles, and windmills. Examples of uses for this simple machine include cars, wagons, and any machine with wheels.
4. Inclined plane - An inclined plane is a simple machine that is a sloping surface used to raise heavy objects. They are used to make it easier to move or lift heavy objects that would be difficult to move otherwise. Examples of uses for an inclined plane include a ramp used for loading and unloading goods, stairs used to climb, and a slide that allows children to slide down.

Simple machine and their uses except lever Pulley and wheel and axe and inclined plane
1. Wedge - A wedge is a simple machine that consists of two inclined planes that are back to back and used to split or lift objects. Examples of uses for a wedge include a knife cutting through food, an axe splitting wood, and a chisel carving into wood or stone.
2. Screw - A screw is a simple machine that consists of an inclined plane wrapped around a cylinder or cone shape. They are used to hold objects together, lift objects, and move materials. Examples of uses for a screw include screws in construction to fasten materials, a jar lid to keep food fresh, and a drill bit for drilling into wood or metal.
3. Gears - Gears are simple machines that transmit and transfer power and motion between machines and equipment. They are used in a variety of machines, including vehicles, clocks, and machinery. Examples of uses for gears include a bicycle chain to transfer power from the pedals to the wheels, a clock to keep accurate time, and a car transmission to change gears for different speeds.
4. Cam - A cam is a simple machine that consists of a rotating or sliding piece that follows a specific shape or pattern. They are used to convert rotary motion into linear or reciprocating motion. Examples of uses for a cam include a sewing machine to move the needle up and down, an engine to open and close valves, and a machine used in manufacturing to stamp out parts.
