1. The Physics of Roller Coasters By Joshua Coyston

4. Hydraulic systems are most commonly used for launch roller coasters, as they provide a constant acceleration during the entire launch. They usually require 8 pumps of approx. 500 horsepower to launch.

5. Some roller coasters use LIM/LSM launch systems, which is where the train is propelled by electromagnets. This creates a very quick acceleration.Hydraulic Motor

7. V stands for Velocity

8. r is the radius of the circle.

10. X is A-B = 23 – 8.625 = 14.375

11. Y, by chance, is also 14.375

12. Z =(X2+Y2) = [(14.375)2 + (14.375)2] = 20.329A=23m Z m So, d=20.329m  r=10.165m. Given that T5s: X m Y m V=(2*10.165)/5 V=12.8 m/s or 28.6 mph (3sf) B m

13. The Clothoid Loop The Clothoid Loop, commonly known as ‘The loop-the-loop’ or a ‘Vertical Loop’, was first used on a roller coaster in 1975 and was designed by Werner Stengel. The main reason for this is because the circular loop causes much higher G-Forces on the body.

14. The Curious Case of Saw’s Differing Radii Red Line – How the track is. Green line – How the should be to prevent a ‘bump’.
