“The height of the pulleys from the ground was twelve yards, and consequently, when the weights had descended through that distance, they had to be wound up again in order to renew the motion of the paddle.”
About This Quote
Source Book: Treatise on Heat, 1852
The mechanism requires resetting after each cycle because the weight descends a fixed distance before being rewound.
In simple terms: The device must be rewound after each use.
Key Takeaway
Reset the system after each operation.
