NO A WHEEL CHAIR IS A WHEEL AND AXEL WHAT I WAS ASKING WAS: IS A CHAIR A LEVER ..stupid thing
steam engine consumes a lot of fuel with pollution it requires maintenance, development and more money for constructionit can not be used everywhere, special arrangements like petrol pumps were not there
Thomas Jefferson.
Factories need transportation to bring in supplies needed inside the factory and to ship what is produced in the factory out to stores, the public, etc. Early factories didn't have the use of railroad and trucking transportation, so the quickest way for these early factories to bring things to the factory and ship goods out of the factory was by water. Therefore, they were built along waterways like rivers.
Aren't all horns located on the steering wheel?
A turbine or water wheel,
In an undershot water wheel, the wheel turns as a result of the weight of the water. The water flows into the wheel, stops and then when the wheel turns the water flows out underneath the wheel. It is used when you do not have a big head of water. In the overshot wheels the water pushes the wheel and then flows over the top of the wheel. The overshot wheel uses both the weight and the momentum of the water and so are more efficient and powerful.
Itsinfo on a water wheel
The sumerians invented the water wheel.
By using the water to drive a turbine or a water wheel or pelton wheel.
Yes, Sumerians did invent the water wheel. In fact the Sumerians invented the wheel.
A water wheel with buckets is called a noria
The water wheel. :)
A water wheel uses the force of flowing water to turn its blades. As the blades rotate, they transfer this mechanical energy to a shaft connected to machinery or a generator, allowing the water wheel to perform work such as grinding grain or generating electricity.

The overshot wheel was an improvement over the undershot wheel because it allowed for creating more force on the water so the wheel moved faster. The undershot wheel has a drag factor because water is gotten at the bottom of the wheel and has to be carried up to the top of the wheel. The overshot wheel has water flowing into the buckets at the top of the wheel forcing it downward.
