What are degradation mechanisms?

Degradation mechanisms are like the reasons why your favorite toy starts to break down over time.

Imagine you have a really cool robot that moves around and plays with you. At first, it works perfectly, it runs fast, it can do tricks, and you love it. But after a while, it might start making strange noises or even stop working altogether. That’s because degradation mechanisms are the things that cause your toy (or anything else) to slowly get worse.

One reason could be that the robot gets too hot from running so much, kind of like how you feel when you run around outside in the sun for a long time. The heat can make parts inside the robot shrink or change shape, making it harder for everything to work together.

Another reason might be that the pieces inside get worn out from being used over and over again, just like your shoes start to wear down after walking all day at school. Little by little, things stop working as well as they did before.

So, degradation mechanisms are like the "why" behind why things break down, even if you don’t see it happening right away!
