Notch (engineering)

Okay kiddo, a "notch" in engineering is like a little cut-out or groove in a piece of material, like metal, plastic or wood. It's like a small, specific part that has been purposely removed from the material.

Engineers use notches for a lot of different reasons. For example, they might use a notch to make it easier to attach two pieces of material together. They might also use notches to make a particular component fit into a larger structure or piece of machinery.

Think of it like playing with Legos. Sometimes, the pieces of your Lego set need to fit together in a specific way. You might have to snap off a little bit of one piece to make it fit perfectly with another. That's kind of like creating a notch in engineering.

Notches can come in all shapes and sizes, from tiny little grooves to bigger cut-outs. They can be created using different tools, like saws or lasers, depending on the material and the specific purpose of the notch.

Overall, notches are just a useful tool that engineers use to make sure everything fits together perfectly and works as it should.
