What is an i-beam?

An i-beam is one of the strongest types of beams. It is one if the best because of its shape, although you can see them almost every where there are differences between them so that they can do different tasks. The main difference between them and what makes them strong is there “web” it’s the strongest part of the beam:

As you can see this is the shape of an i-beam the web (that’s labeled) is pretty tall, but if you make it taller its more strong maybe you don’t want it to be tall because its not holding wait maybe it’s “holding” tension. Not a problem you can line them up in a way that is more suitable for that job.
