Compound Machines
Simple machines can be combined to form compound machines, which are made up of two or more simple machines working together to perform a specific task. Compound machines can be more efficient and effective than using a single simple machine, as they can take advantage of the strengths of each individual component.
Some examples of compound machines include:
- A wheelbarrow, which is made up of a wheel and axle (for rolling) and a lever (for lifting and moving the load).
- A car jack, which is made up of a screw (for adjusting the height) and a lever (for lifting the car).
What Is a Simple Machine?
Simple machines are a fundamental aspect of technology and have been used throughout human history to make tasks easier and more efficient. They are mechanical devices that help us to perform work by applying a force over a distance, and they are classified into six main types: lever, pulley, inclined plane, wedge, wheel and axle, and screw. These simple machines are the building blocks of more complex machines and are still widely used in industry and everyday life.
