Okay so now I have T1 - Mg = M(a1) T2 - Mg = M(a2) a1/R = a2/r T1 = T2(r/R)

EDIT: so from there, assuming that the above equation is valid, α = T2(r/R-1)/M

net torque = radius * tension => 0 = T1R - T2r => T1R = T2r => T1 = T2(r/R) so T2(r/R) -T2 = M(αR-αr) T2(r/R-1) = M(αR-αr) It seems like I am going in circles haha.

Okay. Torque = Iα. However since we are neglecting the moment of inertia of the discs, torque would be 0?

Yea I understand what you mean now. Sorry about that. The problem I am really facing with this problem as evident by my attempt at the solution in post number 4. The question asks to find the angular acceleration, do I just give it as α? or do I derive that from other variables stated in the...

Bump, I uploaded the full problem in attachemtn

bump Here's my working so far: Angular acceleration is the same for both discs = α => acceleration of mass 1 = αR and mass 2 = αr I then drew free body diagrams of the 2 masses with mass 1 on the left and mass 2 on the right. Fnet=ma T1 - Mg = M(a1) - eq.1 T2 - Mg = M(a2) - eq.2 eq1-eq2...

So if I assume that the discs have no mass, we are also neglecting the gravity? I think I am missing something here. I just find it difficult when a question does not give me any quantitative value to work with. I appreciate your help.

Homework Statement Two discs of radius R and r are fixed to each other, i.e., they rotate together. Strings are wound around both discs and two equal masses M are connected to the ends of the strings (see Figure 1). Find the angular accelerations of the discs, the accelerations of the masses...

So using 2) for both balls it becomes: X = 0 + 0(t) + 1/2(a)(t^2) X = 1/2(a)(t^2) t^2 = X/(1/2a) Since XA < XB and aA < aB ... It seems like I have hit another sticking point.

Relevant equations: 1) V=V0 + at 2) X=X0 + V0*t + 1/2a(t2) 3) X=X0 + 1/2(V + V0)t 4) V2=V02+2a(X - X0) How should I work with this?

Ahhh. Thanks for correcting me, it is indeed a force. So the only constant acceleration equation that is independent from time is v2 = v20 + 2ax I will continue from here and update on my progress. Thank you.

Homework Statement Two balls A and B simultaneously start to roll down without friction along two different chords of a circle as shown in the figure. Find which ball will hit the circle first? (image attached) 2. The attempt at a solution I have divided the velocity of the balls into vector...
