Pulleys: Exploring Their Functions and Types

The video tutorial explains the concept of pulleys, highlighting their applications in sailboats and cranes. It describes the basic mechanics of pulleys, which consist of a grooved wheel and a rope or cable. The tutorial distinguishes between fixed and movable pulleys, explaining that fixed pulleys change the direction of force without mechanical advantage, while movable pulleys increase force or effort. The concept of a block and tackle system, which uses multiple pulleys to enhance mechanical advantage, is also introduced.
