A5 1 Rollercoaster Restraint vs Your Spine

Abstract

We investigate the plausibility of falling out of a restraint mid-ride. We determine that a rider would need to exert 35 kN of force (45 Gs of G-force) to the contact, causing the pawls to fail by mode of buckling. At this force, we find the human torso would extend by 7 metres. We find a human would break before the restraint would.
