The central moments of inertia of the gears A and B as shown are 10 kg.m2 and 20 kg.m2, respectively. If the mass of the block C is mC = 50 kg and the system is released from rest, determine alpha A of the gear A

fig is attached

2. Relevant equations

3. The attempt at a solution

I can compute alpha B from the data but how can to compute alpha A? I mean is there an equation related between them?

By the way, about alpha B, did my equation correct?

20 alphaB = 0.15 T

T - Wc = -mC aC

aC = alphaB x 0.15

thx for your helps!!
