Two Masses are suspended from a pulley. The pulley itself has a mas of .20kg a radius of .15m a constant torque of .35 MN due to the friction between the rotating pulley and its axle. What is the magnitude of the acceleration of the suspended masses if m1= .4kg and m2= .8 kg (neglect the mass of the string)

M2 M1

2. Relevant equations

T1= M1G - M1A

T2= M2G + M2A

Torque= FL = Moment of Inertia x Alpha,

I= 1/2 mr^2

3. The attempt at a solution

I have tried solving this by solving for A when T2-T1= I alpha, but i really dont know how to apply the fact that the tension is different of both cords due to the friction on the pulley im stuck...
