How can I make a hanging weight attached to a wire move at a constant speed under its own weight? The mass of the weight may vary and is not known beforehand.
The discussion centers on designing a wire apparatus that allows a hanging weight to descend at a constant speed of 1 m/s under its own weight. The key challenge is to achieve a balance of forces that accommodates varying weights while maintaining this terminal velocity. The proposed solution involves utilizing a variation of a flyball governor, where weights with brake pad material contact a surrounding cylinder to apply braking force as the descent speed increases. Commercially available devices, such as those from Torqhoist, can facilitate this mechanism.
PREREQUISITESMechanical engineers, physics students, and hobbyists interested in designing weight-controlled descent systems or studying the dynamics of motion under gravity.
