What is a compound machine?

A compound machine is a mechanical device that combines two or more simple machines to perform a specific task. By combining multiple simple machines, such as levers, pulleys, gears, and inclined planes, a compound machine can amplify force, increase speed, or change the direction of motion.

Compound machines are often used in everyday tools and equipment, such as bicycles, cars, and manufacturing machinery. They are designed to make work easier by reducing the amount of force or energy needed to perform a task.

One example of a compound machine is a bicycle, which combines several simple machines, including gears, wheels, and pedals, to allow a rider to travel long distances with minimal effort. Another example is a crane, which uses a combination of pulleys, levers, and gears to lift heavy objects.

Overall, compound machines are versatile and efficient tools that play a crucial role in modern technology and industry. They are used in a wide range of applications, from transportation and construction to manufacturing and agriculture.
