A roller coaster climbs the first hill.

It races down the track.

Then suddenly...

It flips upside down.

And somehow, the train stays perfectly attached to the rails.

No falling.

No flying off the track.

Just pure engineering.

So how does it work?

In this episode, we explore the fascinating engineering behind roller coasters and how they safely remain attached to the track through loops, corkscrews, barrel rolls, and other inversions. We dive into mechanical engineering, structural engineering, physics, wheel assemblies, centripetal acceleration, track design, safety systems, and precision manufacturing.

We examine the unique wheel system that makes roller coasters possible. Unlike a train, which simply sits on top of its rails, a roller coaster uses multiple sets of wheels that grip the  ...
