simple machines

1. Inclined plane

1.1. A Inclined plane is one of the six simple machines.It is like a ramp.It is very useful because it makes things easier to lift.It takes less effort to push heavy things up a inclined plane.The inclined plane is a very important machine.

1.1.1. Slide

1.1.2. ramp

1.1.3. slope

2. pulley

2.1. A pulley is one of the six simple machines.A pulley is very useful,because it can lift very heavy things that a human being can't lift.With out this machine our lives would not be easy.For a pulley to work you have to pull down on a string and then something will go up using less effort.If you use two pulleys it would be easier to lift something.

3. wheel and axle

3.1. A wheel and axle is one of the six simple machines.A wheel and axle is very useful, because with out it we can't transport to other places.A wheel and axle help us a lot,because they are on cars,buses,trams,and trains.If we didn't have those voiceless we would not be able to transport easily.A wheel is a circle with a hole in the middle were the axle goes.

4.1.1. slice

4.1.1.1. axe

4.1.1.1.1. scissors

5. screw

5.1. A screw is one of the six simple machines.A screw is just a inclined plane raped around a wedge.A screw is very useful,because it can glou things together.Underneath a screw there is a pointy bit.It is cold a wedge.It has to be pointy so it can make a hole into the wall.The pointy bit is small but it is just the right size.

6. lever
