Of course, that's much more logical. I wanted to take the differential formula of the speed, but that's the hard way I guess.
so the T=FR. F is g(m1+2m2), R is R1. T is R1*g(m1+2m2). T=Ia. the mistake I made in using the parallel axes theorem was that I didn't use all the mass, isn't it? the...
hey, I have a tough time cracking this one
The other problem is:
Imagine a glass tube with steel rings around it which have a conductancy rho and a half diameter of R. they are spaced with a distance H.
inside the glass tube is a much smaller glass tube. Through it you drop a magnet with mass...
an interesting problem
I came along this problem, it is quite interesting. However, I have worked with the problem to long and than you can't see any new ways. So I thought, maybe you guys could try it with a fresh mind. Good luck, it is a tough one (or I fail to see something obvious)
imagine...
