IntroductionSimple machines are devices with few or no moving parts that make work easier.The common examples of simple machines are;-Wedgewheel and axleLeverinclined planeScrewpulley CraneExcavator

Wedge The wedge is a simple machine that forces objects or substances apart by applying force to a large surface area on the wedge, with that force magnified to a smaller area on the wedge to do the actual work.

2. Wheel and AxleThe wheel and axle is a simple machine that reduces the friction involved in moving an object, making the object easier to transport.

3. LeverA lever simple machine consists of a load, a fulcrum and effort (or force). The load is the object that is moved or lifted. The fulcrum is the pivot point, and the effort is the force required to lift or move the load.

4. Inclined PlanesInclined planes make it easier to lift something. Think of a ramp. Engineers use ramps to easily move objects to a greater height.

5. ScrewA screw is essentially an inclined plane wrapped around a shaft. Screws have two primary functions: they hold things together, or they lift objects.

6. PulleyA pulley is a simple machine used to change the direction of a force. Think of raising a flag or lifting a heavy stone.

7. Crane

A Crane is a type of machine generally equipped with a hoist rope, wire rope or chain.Crane can be used both to lift and lower material and to move them horizontally.

Use of craneIt is Mainly used for lifting Heavy things and transportingThem to other place .Cranes are commonly employed In the transport industry for the Loading and unloading of freight In the construction in industry for The movement of material and in The manufacturing industry for theAssembling of heavy equipment.

7. Excavator

Excavator are heavy construction Equipment consisting of dipper, bucket and cab on a rotating platform known as the house.

In excavator mainly used hydraulic mechanism so, it can carry a load very simply.In excavator main parts are hydraulic cylinder and hydraulic motor.
