We have uniform thin rigid disc rolling without slipping on a horizontal rigid plane. A force is applied to its center of mass in a direction along the motion, 30 degrees out from the disc plane. What are a good choice of generalized coordinates for this system in order to furnish Langrages equations? I was thinking (x,y) for the center of the mass of the disc and theta for the angle the central axis of the disc makes with the x-axis for its orientation, but I don't know how to proceed. Thoughts?

That doesn't fucking make sense. How the fuck do you apply a force to the center of mass of a disc? Unless you're applying that force normal to the flat sides of the disc, but then it would fall over. Otherwise, you're going to be applying force to the round side of the disc, but that isn't the center of mass obviously.

I have no idea what you are talking about, and feel offended the first person to respond didn't offer any advice about this problem. If you have a problem visualizing this situation in reality, note that the rigidness of the plane and other such cues clearly define it as a hypothetical exercise. Perhaps you could think of it as a small man or fly hovering close to the center of mass of the disc at the prescriped angle to the disc plain constantly holding a special device that attracts the central atom of the disc in his direction.

So in other words a big fat fucking meme?

If I could ban you from the board and kill you instantly for wasting my time, note I would do so with the greatest of speeds.

kek is that force times a distance.

Yet, you can't. So keep wishing, faggot, and I'll keep shitposting

Veeky Forums exposed for a bunch of brainlets who talk above their belt on shit like quantum mechanics but cant find the motion of a disc rolling
