A wagon typically includes wheels, which are an example of the simple machine known as a wheel and axle. This simple machine allows the wagon to move easily over various surfaces by reducing friction.
A drain stopper in the bottom of a sink is an example of a simple machine called a wedge or sometimes a lever. It functions by either blocking or allowing water to flow through the drain when raised or lowered.
Inclined plane. It lets the water drain out.
Wheels and axles are typically found on the bottom of a wagon. They reduce friction between the wagon and the ground, making it easier to move heavy loads.
They reached to the bottom of their bathtub, next time spell your question right 8=====D~

Wheels and axles would be found on the bottom of a wagon. The wheels reduce friction and make it easier to move heavy loads, while the axles support the weight of the wagon and allow the wheels to rotate.
