1Q20.41 Rolling Up an Incline

A roller is timed as it rolls up an incline under a constant torque produced by a cord wrapped around the axle to a hanging weight.

A narrow, high-rimmed ramp is inclined at a shallow angle on a tabletop. A roller with a long axle sits on the ramp. The roller has an axle long enough to stick out beyond the ramp's rim on both sides. A small hanging mass is wound around the roller. The mass is wound far enough out along the roller's axle that it falls straight without hitting the table.
