The Physics of Roller Coasters Book
by Tony Wayne, VaPEN's Physics Pavilion.
This book shows a simplified view of the design considerations and science a mechanical/civil design engineer must know when designing a roller coaster. It includes labs, assignments to be done at an amusement park, hands on design of a roller coaster, and more. Looks like 150+ pages of fun and physics.
