(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Two blocks are connected by a string of negligible mass passing over a pulley of radius .25 m and moment of inertia I. Block 1 is on an incline of 37 degrees and block 2 is hanging down. The hanging mass is accelerating down at 2 m/s^2. Find I. (I already know tensions T1 and T2)

2. Relevant equations

Tnet = I*[tex]\alpha[/tex]

3. The attempt at a solution

T1(incline block) = 118 N, T2(hanging block) = 156 N

So,

.25*156-.25*118cos(37) = I(2/.25)

I think you need the cos(37) because T1 (on the incline) has a vertical component that does not contribute to the torque. Is that correct?
