Henri Tresca
Henri Tresca was a very smart man who lived a long time ago. He was really interested in how things were made and how they worked. He studied a lot about rocks and metals, and he figured out how to make machines and buildings stronger and safer.
One of the things Henri Tresca is most famous for is something called the Tresca Yield Criterion. Now, that's a really big and fancy name for a rule that helps engineers and builders know when a material, like metal or rock, is going to break or bend under pressure.
Basically, the Tresca Yield Criterion says that when something is pushed or pulled really hard, it will start to change shape. If it's a metal, it might start to bend, and if it's a rock, it might crack. But before that happens, there's a certain amount of pressure that the material can withstand. That's called the yield point.
Henri Tresca came up with a way to calculate the yield point using some fancy math. And that's really useful because it helps engineers and builders make sure that the things they design, like bridges and airplanes, are safe and won't break under pressure.
So, in a way, Henri Tresca helped make the world a little bit safer and more awesome!
