Table of Critical Points 

We decided to begin the design of the roller coaster at 200 meters so that we could continually go downward and have the roller coaster speed up. Because of this we encountered trouble finding points with proper radii. Because we were ignoring friction, the loops had to gradually get larger as we descended in order to not harm the riders. That is why our loops and curves get larger and larger as the roller coaster got closer to the ground. Our last loop ended up having an incredible radius of 75 meters in order to be under the max limit of G's.

Come one! Come all! Introducing the one and only Flying Bell Rollercoaster! Named for the world famous 150 foot loop, the Flying Bell will leave you with the sound of bells ringing in your ears for hours after the ride. For older-aged individuals, this ride will be one that you will remember forever with its clothoid and circular loops that will have you feeling forces up to 5 g's. Come along for the ride and experience heights up to 200 meters and drops up to 60 meters. This ride will have your breathless with speeds topping 45 mph and winding turns that have you feeling the cool breeze at every corner. So, prepare yourself for the ride of your life and come along with us!

And remember:

"Life is a rollercoaster! Enjoy the ride!"

Day 3

Preliminary Spreadsheet

Final Spreadsheet

Today, we finished the Excel spreadsheet and pasted our data into the blog. Overall, our forces remained under 5 g's and the heights, distances, and velocities are sufficient enough to keep our riders safe.

Day 2

Preliminary Poster Design

Final calculations and critical points

Today, we finished the final graphing design and poster board design of the rollercoaster. Although the drawing is a sketch, the points are accurate and the loops exert the right amount of g's (under 5 g's) for our riders.

Day 1

Preliminary calculations and critical points

Today, we started to graph the critical points on the small sheets of graph paper. During this process, we stumbled upon force exceeding 5 g's, which would kill our riders. In order to avoid this problem, we changed the sizes of our loops and managed to stay under 5 g's.
