Features of a rollercoaster

Here includes research of various features that might be included in the rollercoaster.

• Banked turns - A banked curve induces a sensation of being thrown sideways by turning the car sideways. The car is tilted, but the trick is to tilt the track just the right amount. Wayne, Tony . (2000). Curves. Available: http://vip.vast.org/BOOK/CURVES/HOME.HTM. Last accessed 13/10/15. 
  

• Vertical loop - The generic roller vertical loop can either be in a circular or teardrop shape. It is where a section of the track completes a 360 degree circle, is the most basic of roller coaster inversions. At the top of the loop, riders are completely inverted. Rollercoasters today employ clothoid loops rather than circular loops. This is because circular loops require greater entry speeds to complete the loop. If the radius is reduced at the top of the loop, the centripetal acceleration is increased sufficiently to keep the passengers and the train from slowing too much as they move through the loop. Berry, Nick.

• Corkscrew that has three helices - A corkscrew is an inversion that resembles a vertical look that has been stretched so that the entrance and exit points are a distance away from each other. It includes three loops in a row. Wikia. (2004). Inversion . Available: http://rollercoaster.wikia.com/wiki/Inversions#Vertical_Loop. Last accessed 14/10/15.
