Answer 2

Answer:

A wheel is a disc- or circle-shaped mechanical device. Its main purpose is to allow things to roll; in other words, the wheel spins, and objects on the wheels move more easily along the ground. It is a simple machine.

Explanation:

THE WHEEL is often described as the most important invention of all time – it had a fundamental impact on transport and later on agriculture and industry. ... Soon, it became common for the wheels to turn around a fixed axle. Wheels with spokes, first made around 2000 BC, were lighter, enabling vehicles to move faster.

Everyday examples of this type of wheel and axle include:

• Bicycle
• Car tires
• Ferris wheel
• Electric fan
• Analog clock
• Winch
• Screwdriver
• Drill
• Windmill
• Water wheel
• Doorknob
• Pizza cutter
• Skateboard

I have included axel also because wheel and axel are common, but give the definition of wheel.
