Replacing a valve stem.

A valve stem is a self-contained valve which opens to admit gas to a chamber (such as air to inflate a tire), and is then automatically closed and kept sealed by the pressure in the chamber, or a spring, or both, to prevent the gas from escaping.

They are most commonly used on automobile, motorcycle, and bicycle tires, but also for many other applications.

China, officially the People's Republic of China (PRC), is a country in East Asia.

It is the world's most populous country, with a population of more than 1.4 billion people.

China spans five geographical time zones and borders 14 countries, the second most of any country in the world after Russia.

Covering an area of approximately, it is the world's third or fourth largest country.

The country consists of 23 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau).

The national capital is Beijing, and the most populous city and financial center is Shanghai.

These water valves are operated by rotary handles.

A valve is a device or natural object that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways.

Valves are technically fittings, but are usually discussed as a separate category.

In an open valve, fluid flows in a direction from higher pressure to lower pressure.

The word is derived from the Latin valva, the moving part of a door, in turn from volvere, to turn, roll.

An early wheel made of a solid piece of wood.

A wheel is a circular component that is intended to rotate on an axle bearing.

The wheel is one of the key components of the wheel and axle which is one of the six simple machines.

Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines.

Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel and flywheel.

Display of agricultural tools.

A modern toolbox.

A tool is an object that can extend an individual's ability to modify features of the surrounding environment.

Although many animals use simple tools, only human beings, whose use of stone tools dates back hundreds of millennia, have been observed using tools to make other tools.

Early tools, made of such materials as stone, bone, and wood, were used for preparation of food, hunting, manufacture of weapons, and working of materials to produce clothing and useful artifacts.

The development of metalworking made additional types of tools possible.

Harnessing energy sources such as animal power, wind, or steam, allowed increasingly complex tools to produce an even larger range of items, with the Industrial Revolution marking a marked inflection point in the use of tools.

The introduction of automation allowed tools to operate with minimal human supervision, further increasing the productivity of human labor.
