Pulleys with Mass
Watch it explained
- How it worksHow does a massive pulley end up with different rope tensions on its two sides?
- How it worksWalk me through writing one force equation per block and one torque equation for the pulley.
- Worked exampleFind the acceleration of a 4 kg block on a table pulled by a 2 kg hanging block over a 1 kg pulley.
- Common mistakeWhy doesn't the tension stay the same on both sides once the pulley has mass?
