Second Newton's law in rotation with pulley.

[QUOTE="haruspex, post: 5481739, member: 334404"] I don't understand the information given regarding frictional moment. We are told that the rope does not slip, we know the two suspended masses, and we know the moment of inertia of the pulley. Assuming this is in Earth's surface gravity, g, there is enough information to find the torque the rope exerts on the pulley. And it will not oppose the angular speed of the pulley. The only way I can make sense of the problem is if it should have said that the [B]axle[/B] exerts that frictional torque opposing the rotation of the pulley. Assuming that is what the question said, check the signs in your equation for the pulley's acceleration. Is T[SUB]1[/SUB] tending to make the pulley rotate faster or more slowly? [/QUOTE]
