*Inclined Planes, Wedge, and Screw

An inclined plane is a sloped surface that makes work easier by breaking down a movement into smaller incraments. I used a ramp in my picture for the inclined plane. The load is the car and the effort is the engine to make it go. Other inclined planes are stairs, hills, and slides.
Another simple machine is a wedge. It is two inclined planes placed back to back to make work easier by breaking jobs into smaller parts. I used a knife cutting an orange, with the person holding the knife as the effort and the load as the orange. An ice scraper is also an exampe of a wedge.
The screw is an inclined plane wrapped around a cylinder. In my drawing for a screw the effort is the screw driver and the load is the wood it's cutting into.
