Homework Statement
Two objects are attached to ropes that are attached to wheels on a common axle as shown below. The two wheels are glued together so that they form a single object. The total moment of inertia of the object is 41 kg·m2. The radii of the wheels are R1 = 1 m and R2 = 0.4 m.
(a) If m1 = 24 kg, find m2 such that there is no angular acceleration of the wheels.
(b) If 12 kg is gently added to the top of m1, find the angular acceleration of the wheels.
Homework Equations
T=I(alpha)
alpha=change in velocity/ change in time
The Attempt at a Solution
I'm not really sure where to start for this. I know I need to figure out the Tension for the block, but I'm not sure how to go about doing this.
