A block and tackle is a system that uses a combination of pulleys (blocks) and rope (or cord) to lift heavy loads more easily. The basic components include: 1. **Blocks:** These are the stationary and movable parts containing the pulleys. A typical block consists of one or more wheels (pulleys) through which the rope is threaded. 2. **Rope or Cable:** This is the line that runs through the pulleys.
