Question
In the situation shown, a heavy wheel with a small drum attached is suspended by its frictionless axle from a ceiling. Attached to strings around the rims of the wheel and drum are two blocks of equal mass. The system is originally at rest. When the blocks are released.
- Nothing happens, since the blocks have equal mass.
- The right hand block falls and the left hand one rises, with accelerations of the same magnitude.
- While the blocks are moving, the tension in the right hand string is less than that in the left hand string
- Which block falls depends on the moment of inertia of the wheel-drum system.
The correct answer is: The right hand block falls and the left hand one rises, with accelerations of the same magnitude.
