Homework Equations
Ʃ[itex]\tau[/itex] = I[itex]\alpha[/itex]
ƩF = ma
The Attempt at a Solution
I was able to calculate A and B which I am confident is correct..
for part C is what I'm having trouble with. Since both disks are fixed together, does that mean they share the same angular acceleration? if so I think the way to go about this is I apply the equation
Ʃ[itex]\tau[/itex] = I[itex]\alpha[/itex]
where it will be T1R1 - T2R2 = I[itex]\alpha[/itex] and I just solve for alpha.
but since they are now accelerating.. doesn't that change each tension to be t = mg + ma? instead of just t = mg ? which then makes it much more difficult to solve..
unless if the tensions are just mg then it will be fairly easy to solve since I can find the alpha of the rotating system then just apply the equation
a = [itex]\alpha[/itex]R
and calculate the a for each, and from there I will be able to find the tensions in each rope.
