  • Matt and Hugh play with an Euler Disk which spins forever. Then they do some working out to check Matt’s previous calculations.
    Matt’s previous video: The Maths of Spinning Coins and Euler's Disk
    • The Maths of Spinning ...
    Sadly we don’t have Euler Disks on Maths Gear but it is of course on Amazon:

    Dr Hugh Hunt is a Senior Lecturer in Engineering at the University of Cambridge and a Fellow of Trinity College.

    This is a new video format idea, so all feedback appreciated.

      friction results in flattening the system and making it wobble less so the wobble is approaching 0, and in the non perfect reality approaching 0 actually approaches 0 quite fast

      I think 6:1 might depend on the composition of the object... Depending on the material that is used; its density, its surface texture {smoothness or roughness}, the amount of friction that it applies, and other properties that can be leading factors this ratio could change.

      This is the reason that the guys that know sh*t don't whine.
      They enjoy the fact they could be wrong, and revel in the fact they could be right. Having a conversation on your own level, be it mud pies. machinery or quantum physics is exciting for all involved. There's some human distraction from this perfect scenario however - it's not often you hear of two or more people discovering things, each will go about it their own way, which is even better - till some guy who is out of sight comes from their research and scoops it all up and makes something new.... it's all awesome. Gotta love it.
      I'm as thick as pig sh*t but I love trying my own dumb ass ways, fumbling around in my shed or on paper. I get giggles when I meet someone who has been through the same neanderthalic methods as myself and there's some unity.

  • @mathmachine4266
    @mathmachine4266 Před 3 lety +1

    Math Machine
    I did some maths. I assumed the disc is of uniform distribution, there's no rolling friction, and there's no air resistance. Under these conditions, I believe the disc should remain at a constant angle from the horizontal.
    The rate at which the disc spins around the vertical axis is equal to √(6g(2rcos(θ)-hsin(θ))/(sin(θ)((3r²+4h²)cos(θ)+6hrsin(θ)))), where h is the thickness of the disk.
    Assuming the height is small compared to the radius, this leads to a rotation speed of 2√(g/(rsin(θ))), and assuming θ is small, this gives your approximation of 2√(g/(rθ)).
    In addition, the rate of rotation of the dot placed on the disc is equal to the rotation speed around the vertical axis, multiplied by cos(θ).
    A small note, according to the formula I provided, the rate of rotation when θ=π is √(g/r). Technically, the disc could rotate at whatever speed it wants at this angle, as it's technically in equilibrium. However, if the angle were slightly below π, it would need to have a rotational speed of about √(g/R) in order for it to not fall into either the vertical position or towards the ground (depending on how stable the θ=π equilibrium is).

    I think you and Brady should introduce Hugh to Cliff Stoll. They'd get on like a house on fire, I feel. Could be the start of a new science CZcams duo in fact!

    It's a wonder I got interested in math. Every single math teacher I ever had absolutely STUNK. I ended up totally pissing off my algebra teachers by reading books in class because they sucked so bad, but passed because I taught myself using a programmed algebra system.

    I have the exact same Euler disk that you guys raced with at the end and I spun mine at the same time as your race. Mine lasted about 27 seconds longer than either of yours.

    Love that final sound, like a little engine lol Another interesting thing on that you could see who was going to win, because there was a circle of light reflecting from both disks when the camera was equidistant from them, and Matts circle was larger than Hughs (higher angle) lol. Interesting experiment.

    If you substituted a high-polished tungsten circular disc with an elliptical cross-section, your air-blown contraption would make for a brilliant movie prop involving a time travel engine.

    The graph (drawn on the paper) was supposed to go from y=1 at x=0 to y=positive infinity at x=pi/2 if you're considering only 1/cosx where 0

    BTW, I noticed that here is the difference between maths and Engineering: 9:54 and 11:31
    I personally prefer engineering but I realize that they both are beautiful in their own ways.

    For measuring the angle on his air assisted rig, could it be filmed with a high speed camera and a series of angles marked in the background (similar to a protractor) and then choose the frame from the footage that has the plane of the disc perpendicular to the camera?
    That way you get a still image with the angle on it, and can get a more exact measurement than using the rubber finger thing and stopping when it looks close enough.

    Can you tell me how many wobbles the disk is doing totally? Is it infinity? How many wobbles after second spin?

    Hey Matt, what about the diameter of the 2 circles, can you deduce the disks height and thus all the information like beta dot, theta, and omega
