Translation: Determinate, for the system of Fig. 10-39 the angular velocity of the disk and the linear velocity of m and m'. Calculate the tension in each string. Suposse that m = 600 g, m' = 500 g, M = 800 g, R = 8 cm and r = 6 cm.

2. Relevant equations

3. The attempt at a solution

The problem is I don't know to get the moment of inertia because I have the mass of one disk only.
