AI Thread Summary
A user has created a K'NEX rollercoaster using a Fushigi Gravity Ball instead of traditional K'NEX cars, inspired by a design concept during chemistry homework. Feedback highlights the importance of structural rigidity to prevent the ball from falling off the track, especially if scaled up. The user successfully adapted existing designs for the initial lift and plans to incorporate a vertical lift in a more complex version. Concerns about stability during curves were addressed, noting that the ball moves slowly around them and the substructure is robust. The discussion emphasizes innovation in design while maintaining functional engineering principles.

Hello Physics Formums, because of constructive feedback I have decided to create a K'NEX Rollercoaster that uses a Fushigi Gravity Ball instead of the standard K'NEX cars. I thought of the design while I was doing chemistry homework, and after I finished my homework I got to work. Two days later I completed it! Here is the video.

Thank you and please comment with any questions!

I like it, :smile: This time your structure is very rigid. Good for you.
If it was very much bigger, it may not be rigid enough and the ball might fall off the track. How would you improve that?

You also did well adapting existing roller coaster designs for lifting the car up the first hill. No need to reinvent the wheel if you don't have to.

If you decide to study engineering, I think you'll do well.
 
Thank you anorlunda, I plan to make a larger more complicated rollercoaster. I think that a vertical lift would be very efficient.

How to prevent it from shaking when the ball goes around the curve?

The ball never goes around a curve very fast and I built the substructure very substantially.
 
Here is a time lapse of the above video

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
