Thank you for your response.
So why does the solution I have seen for this problem look like it uses ½MR2? I don't think it makes sense to apply the parallel axis theorem in this situation. The hoops are rotating about their centers right? And applying the parallel axis theorem can only make...
Thank you for your response.
I am sure about equation 1 because I have seen the solution and these four equations can be solved together to determine the correct expression for τ. I thought it made sense that the actual acceleration of the hoop would be the difference between the acceleration...
I have seen the solution to this problem but I don't understand it.
Here is my drawing of the problem.
Apparently I should do the sum of the forces and sum of the torques for both hoops like this:
hoop 1:
(1) τ - M1g = M1(a1t-a1R)
(2) τR1 = ½M1R12a1r/R1
hoop 2:
(3) M2g - τ = M2(a1t+a2r)
(4)...
