I-beam

Imagine you have a long stick. This stick is really important because it’s going to hold up a really heavy bookshelf. But you don’t want the stick to break or bend because the bookshelf might fall and that would be really bad. So, you need to make the stick stronger.

An I-beam is like a stronger stick, but instead of being round or square, it’s shaped like the letter “I”. The top and bottom parts of the I are called the “flanges” and the long vertical part is called the “web”.

The reason the I-beam is stronger is because of how it’s shaped. The flanges help to spread the weight out over a larger area, and the web helps to keep the flanges apart. This means that the I-beam can hold up a lot more weight than a regular stick, and it’s less likely to break or bend.

I-beams are used in lots of different things, like buildings, bridges, and even roller coasters! So, if you ever need to build something really strong, you might use an I-beam to help hold it up!
