Capstan theory

Capstan theory is a principle used to understand how a capstan (a drum-like device used to pull heavy loads) can amplify force. Essentially, it describes how the friction between a moving cable and the capstan allows a relatively small force applied at the end of the cable to lift or pull much heavier weights. The theory highlights factors such as the angle of the cable around the capstan and the number of turns the cable wraps around it. Understanding this theory is crucial in fields like engineering and mechanics, where efficient force application is essential.
