Block and Tackle

Block and tackle is a system of pulleys used to lift heavy objects more easily. It consists of a fixed pulley (block) and one or more movable pulleys (tackles). By using this arrangement, you can reduce the effort needed to raise a load, as the pulleys distribute the weight and provide mechanical advantage. For example, pulling down on a rope attached to the tackle can lift an object, making it much simpler to move heavy items without requiring as much force. This system is commonly used in construction, sailing, and various lifting applications.
