Here is a report that I did on a simple machine called a nail.

    

 

     

Nails

Nails are a simple machine. They are considered to be a wedge. This is because a wedge splits things up. You might be thinking how could a nail split something? Well. The answer to this is that if a nail is nailed to something, for example wood, it will make a hole in the spot it is nailed to. So, when this happens, the wood that was in the place where the nail has been nailed is split up to make room for the nail.

If you have never seen a nail, I am sure that you are wondering what it looks like. Well here is a picture of a pile of common nails.
As you can see, one end is flat and the other pointed. There are also other types of nails such as the shoe nail, upholstery nail, staple, tack, and many more. They also come in different sizes.

The nail is made up of three parts, the head, body, and point. Nails are made out of things like chopper.

They are used for putting constructional things together. Usually it is used to put wood together when constructing something.

To use a nail, you have to have a tool called a hammer.
Using the hammer, you need to hit the nail. You can do this by holding the hammer handle, placing the nail where you want it to be nailed then holding it in place, then you need to hit the nail several times until it cannot go any deeper.

By finding out about how a nail works, you can get information about why the nail is shaped the way it is. Well, this is because you hit the nail with the hammer on the flat end. While the point of the nail is the one that makes a hole.

So, I think that nails can sound more interesting then they seem.
