Many extreme roller coaster these days have vertical loops. Have you noticed that these loops are never circular? Why is this?
They all, also, seem to have the same similar ‘inverted teardrop’ appearance. Why is this?
Clearly there is the same physics and mathematics involved in their designs. Let’s take a look and see if we can derive a formula to describe their shape.
Why are roller coaster loops not circular?
