Extrados for Dummies

Alright, so "extrados" is a term used in architecture and engineering, and it can be a bit tricky to understand at first. But don't worry, I'm here to help break it down for you. The word "extrados" refers to the outer curve or surface of an arch or a vault. It's like the outside edge of a rainbow - it's the part that you can see from a distance, and it's what gives the arch or vault its characteristic shape.

Think of it like this: imagine you're building a bridge, and you want to create a strong, sturdy arch to support the weight of the bridge. The extrados is the part of the arch that faces outward and is visible to everyone who crosses the bridge. It's like the "face" of the arch, and it's what gives the bridge its unique appearance.

In simpler terms, the extrados is the outer part of an arch or a vault, and it's what you see when you look at the structure from the outside. It's an important part of the design and construction of buildings and bridges, and understanding its role can help you appreciate the beauty and functionality of architectural structures.

So, to sum it up, "extrados" is the outer curve or surface of an arch or vault, kind of like the outer edge of a rainbow. It's what gives the structure its shape and strength, and it's an important element in the world of architecture and engineering. I hope that helps you understand the concept a little better!
