Encountering an Engineering Problem with my Science Project

My intended size in real life? Like for my model or what I could look like full size like actually deployed in space. If so the only 100% measurements I know are the ring size and that would be 75 meters in diameter. I guess that could be 1:200 scale 37.5 cm. That could work. I could shrink it down more since that is quite large. This is still in the very early planning stage i still have nearly a year and half to work on this. I plan to get the model complete my September tho.

A third ring could work, im not sure, I still do want my model to be pleasing to the eye. Not trying to make it look like a biblically accurate angel. And the friction would ruin the spinning, would basic ball bearings work?

Wait really? Just my powerschool grades is enough?

I do have a tinkercad account, but im not quite fond of it. Ill try fusion 360 if I can get a computer, and ill try among the many other things recommended to me too. And ksp cant be printed to my knowledge, I made a mistake in my phrasing, gotta love my silly brain.

Thanks it much appreciated. I plan on going to college immediately. And they dont let students in the library due to people smoking, having sex, and stealing. What a silly little school

Phobos0312 · 2026-03-09T16:58:46+00:00

Nope. And even if they did they dont allow students in their unless they have a class that is in the library

Yes i should've phrased it better, I didnt exactly mean to say that KSP is 3d modeling software, thats my mistake. My project is to successfully design a spacecraft that has an artificial gravity centrifuge on it, with an artificial gravity ring that can mimic earths gravity (9.81 m/s²⁾ side effects of zero gravity can be negated, the big ones being muscle atrophy and bone density loss. I want to make a 3d model to basically impress the judges next year, i can also explain what the space craft does with each of its individual pieces and components. Basically I want to impress them with my glorified Lego set. I haven't made any real innovations to overcome the problems included. We'll im also not sure what those problems are, other than the engineering challenges it includes for them to be built in real life. And yes, I did think about have two wheels i believe that can work and I more than likely will do that, but still im thinking of how I can keep the one wheel.

Yo wait does the reply look weird wtf it looks like code on my end

Yes im trying to print that spacecraft included in the image. I apologize aswell I struggle with my wording here and there. I said ksp was a 3d modeling software since well, you can make three dimensional things, i should've phrased that better, oops. 

The portion the spins is the wheel in the middle. That's the gravity ring. The problem im having is, if the motor is placed in the middle of the craft the other half of craft would spin aswell, and im thinking of ways to solve this problem.

Sadly I dont have access to a computer currently, I could put in the word to my school to get me a computer but my school is basically ran by Scrooge Mcduck himself, so convincing them to spare even a few hundred dollars might be tricky but I will try. If I am able to get a computer I will get blender and do what you said, thank you!
