INTRODUCTION-: Roller coasters are thrill rides that operates like a railroad track. The history of this ride reflects a constant search for greater and more death-defying thrills. They are made from steel or wood and comprise a series of hills and drops, sudden turns, track loops and corkscrew-like elements. Roller coasters don’t have engines, they must be pulled by a motorized chain to the top of the first big hill. As the roller coaster rises higher, its potential energy increases and reaches maximum at crest of hill. The potential energy accumulated by the rise in height is transferred to kinetic energy as the cars race down the first downward slope.
The contesting teams should design and build a roller coaster meeting the requirements specified in these rules. The roller coaster shall mean the entire structure, including the roller coaster track and the base, but not the actual vehicle. The COASTER shall mean the vehicle that travels on the Roller Coaster track. PROBLEM STATEMENT-: The event will be on the spot and you are required to finish it within the given time frame. Materials will be provided by the organizers.
a) Event is open to all.
b) Maximum team size is 3.
c) Participants can form teams from different branches/ college/ university/ institute.
d) No two teams must have any common member.
e) Teams are not allowed to touch their model once the ride begins.
f) The time limit for the completion is 210 minutes.
g) The decision of the judges shall be final. Any coaster that violates the rule above or the spirit of the competition will be disqualified .
1) Time (30 Points)
Each model will be entitled to three runs. The longest time to go from the start position to the finish will be the official time for that model. Calculation of Points for Time:- Points will be relative. Points = (Your time/max time) * 30 For example: if your time is 22 seconds and max time = 31 sec, then you will get marks = (22/31)*30
2) If any team completes the task before 210 min. then that team will get extra points.
3) Technical points (45 points)
a) Horizontal curves (10 points) Points = (sum of the diameter of your horizontal curves/ maximum sum of diameters) *10
b) Vertical curve (10 points) Points = (sum of the diameter of your loops / maximum sum of diameters) *10
c) Thrill (10 points) Is the track open for all/part of the ride? How abrupt are any changes in motion? Are there any jumps?
d) Vertical Jump Height (10 points) Height the Coaster travels during jump. H = Max height Coaster jumps in any Roller Coaster in competition. h = Height jumped by your Roller Coaster. Points = (h/H) * 10
e) Start Height Bonus (5 Points) For 5 cm less height of Roller Coaster you will be awarded 1 point, max allowed SHB point is 5. Max allowed height of Roller Coaster = 200 cm Height of your Roller Coaster =190(in cm) SHB = (200-190)/4 (2 Points will be awarded)
f)Creativity and complexity (10 POINTS)
Is there anything unique about this roller coaster? You may use items not made from paper for this. Points will be awarded for addition of interesting events like free fall of marble, use of elevator, two or more marble tracks etc.
