Question

An experimental system consists of the solid cylinder of mass m and radius R that is able to rotate around its axis and is attached to the ceiling as shown. Two blocks of masses m1 and m2 are connected by a light, non-stretchable rope as shown. There is no slippage of the rope on the cylinder. Find the angular acceleration ? of the cylinder and the ratio of tension forces T1/T2 of the vertical portions of the rope while the blocks are moving. What is this ratio if mass of the cylinder m=0?

I know how to do T1/T2. I just need help with finding angular acceleartion. I know alpha=2(T1-T2)/MR. I need help from there.

Explanation / Answer

after that finding tensions

T1 and T2

do like this

torque =I=rF

mR2 =R(T2-T1)

=R(T2-T1)/mR2
