Explanation: Why aren’t roller roaster Loops circular?

The clothoid loop has a radius that’s way bigger at the bottom than it is at the top. That is the key to the clothoid loop being a success rather than the roller coaster failing and not going across the whole loop. The amount of curvature at the bottom of the loop is also less than at the top of the loop. These are the two main reasons behind the physics of a clothoid loop but another very important aspect of it is the velocity needing to be high enough to go across the loop as well.

Reflection:

I learnt a lot about how clothoid loops work and the science between them being able to stay in the air. I find it very interesting how roller coasters work and would like to learn more about other rides.
