Homework Statement
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

Homework Equations
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!
