Atwood's Machine Problem with a Pulley of Non-Negligible Mass and Friction in It's Axle.

You make these problems so much easier to do. Thank you. Making the friction work (of the axle acting on the pulley wheel) internal to the system allowed you to set up that final equation so directly and succinctly. Well done as always.
