Question:

who invented the wheel and axle?

so who did

Answer:

God. Actually it was so long ago, it isn't recorded anywhere. Here's some facts: One of the earliest was the potter's wheel, which first appeared in Egypt around 3000 B.C. Wheels have also been used as winches to draw water up from wells or anchors up onto a ship, as waterwheels and windmills to generate power, as grinding mills, as pulleys, and as spinning wheels for textile workers. Perhaps the most common use of the wheel, however, has been in transportation. Sometime before 3500 B.C., people in Mesopotamia began to use sleighs-like vehicles to increase the load their beasts of burden could carry. By 3500 B.C., the runners of the sleighs had been replaced with disk wheels fixed to an axle to which a cart body was attached. The earliest examples of these inventions are two- and four-wheeled Mesopotamian chariots. At first, wheels were made of wood planks fastened together, then cut into circles and often bound with cross-struts. Natural knot-holes were frequently placed in the center to serve as holes for the axle. Around 3000 B.C., rims, made of wood studded with nails or metal strips, were added to the wheel. Between 2000 and 1000 B.C., spoked wheels came into use in Mesopotamia, Egypt, China, and Scandinavia. Spoked wheels were much lighter and could be made with a larger diameter, allowing chariots to be driven at high speeds over rough ground--which made them well-suited for use in battle. The axles and rawhide bearings of these vehicles were lubricated with animal fat, vegetable fat, or mineral oil. Nuff said?

The answer to this is lost in the sands of time. There are many candidates for the first appearance of the wheel, but it is likely that none are the earliest and that they were invented in different places at at different times. Evidence of wheeled vehicles appears from the mid 4th millennium BCE, near-simultaneously in Mesopotamia, the Northern Caucasus (Maykop culture) and Central Europe. The earliest image is from Poland around 3500BCE

Are you referring to the flexible plastic hose type of water line? It is made from polyethylene. In my opinion it is way better than copper. copper can corrode and develop pin holes. Polyethylene is cheap, strong and will last. It is cutting edge.
