A wheel and axle is a simple machine that consists of two parts: a wheel with a rod (called an axle) through its center. When the wheel is turned, the axle turns too, helping to move or lift objects more easily than you could do on your own. You can find wheel and axles everywhere - on bikes, cars, trains, and even in door handles!

Wheel and axle is a simple machine consisting of two wheels connected by an axle. The axle is held up by supports called bearings. The wheel and axle work together to move a load. The wheel turns the axle, which in turn rotates the load. The wheel and axle increases the mechanical advantage of the load, making it easier to move across a surface.
