FSMs sound like something I need to research more! Thanks! For the reflective sheet, I am thinking 11" X 11 ". Anything slightly above or below will do as well. For the vibration, I am thinking of something like the magnitude of a vibrating cellphone (please excuse my limited knowledge...

I thought about that but the mirror would not be able to stand the vibration that I am going to subject the surface to. I should have stated that in my request, but I appreciate the fast response.

Hello Physics Forums goers: Ok, I have a project that deals with image analysis. The idea is to make the process very easy upon myself and make the background on which I will place objects as dark as possible. 1st idea I have is that of a surface that will polarize light when light reflects...

:smile: so, we have non-linear differential equation in two variables (not counting t).. \DeltaU + \DeltaKE = 0; m1 gr( cos (\theta) - cos (\theta0) ) + 0 + 0.5*(m1[(dr/dt)^{2} + (rd\theta/dt)^{2} ] + m2* (dr/dt)^{2}) = 0; 0 = k1 + k2 * cos(\theta) + k3 * r *^{'}^{2}\theta + k4...

so the velocity of m2 would be dr/dt. what is the velocity of m1? it can not be dr/dt because it is also swinging. What value of velocity would u use for the calculation of its (m1's) kinetic energy? P.S> tiny_tim: *I appreciate the quick response* p.s.s> I will post my solution for the case...

Thanks Tiny Tim. --- I had this question posed to me few years back. Sorry if I am not clear on the problems I ran into. (BTW: Pendulum - m1 - is not attached to the pulley but is descending to the ground as it pulls m2 with it while at the same time swinging)

This is not a homework problem. It was a problem posed by my professor at the end of the semester but had me puzzled for a while. I was able to satisfactorily solve it for the case when gravity is not present but I was not so successful with gravity. The question is: to determine the...
