Pulley systems require the synchronized movement of all pulleys. How can pulleys escape this rule?
Pulleys using twisted belts may move in opposing directions.
To violate this rule, pulley system belts must be reversed.
To violate this rule, pulley systems may be used in conjunction with gears.
This rule cannot be effectively violated.
Detailed Explanation
The design of pulleys prohibits the pairing of pulley and gear, and a simple reversal of belts will result in synchronized reversal of all pulleys. To violate this rule, a belt must be twisted.
