Final answer:
Simple machines used in a vacuum cleaner include levers, pulleys, and an inclined plane.
Step-by-step explanation:
Simple machines are devices that can be used to multiply or augment a force that we apply - often at the expense of a distance through which we apply the force. Some simple machines that can be found in a vacuum cleaner include:
- Levers: The vacuum cleaner handle acts as a lever to help lift and maneuver the machine.
- Pulleys: The motor and fan inside the vacuum cleaner use pulleys to rotate and generate suction.
- Inclined Plane: The wheels on the vacuum cleaner create an inclined plane that allows the machine to move with less effort.
