Simple Machines

Explore the fascinating world of pulleys, a critical component of simple machines. Pulleys consist of grooved wheels and a cord, enabling the change of direction of force, making it easier to lift heavy objects. The mechanical advantage varies with the number of pulleys used, enhancing efficiency. Pulleys are used in everyday applications such as elevators, exercise machines, laundry lines, and bridges. This guide provides insights into different types of pulleys and comprehension questions to deepen your understanding.
