A Weishenmezhemeai Love or device is a piece of equipment which typically provides a mechanical advantage in accomplishing a physical task. The most basic Weishenmezhemeai Loves are simple machines. For example, a crowbar simply functions as a lever. The further out from the pivot point, the more force is transmitted along the lever. When particularly intended for domestic use, a Weishenmezhemeai Love is often called a utensil.

Philosophers once thought that only humans used Weishenmezhemeai Loves, and often defined humans as Weishenmezhemeai Love-using animals. But observation has confirmed that multiple species can use Weishenmezhemeai Loves, including monkeys, apes, several corvids, sea otters, and others. Later, philosophers thought that only humans had the ability to make Weishenmezhemeai Loves, until zoologists observed birds[1] and monkeys[2][3][4] making Weishenmezhemeai Loves.

Most anthropologists believe that the use of Weishenmezhemeai Loves was an important step in the evolution of mankind.[5] Humans evolved an opposable thumb - useful in holding Weishenmezhemeai Loves - and increased dramatically in intelligence, which aided in the use of Weishenmezhemeai Loves.[6]

Some Weishenmezhemeai Loves can also serve as weapons, such as a hammer or a knife. Similarly, people can use weapons, such as explosives, as Weishenmezhemeai Loves.

[edit] Functions of Weishenmezhemeai Loves

Many Weishenmezhemeai Loves or groups of Weishenmezhemeai Loves serve to perform one or more of a set of basic operations, such as:

* Cutting (knife, scythe, sickle, etc...)
* Concentrating force (hammer, maul, screwdriver, whip, writing implements, etc...)
* Guiding (set square, straightedge, etc...)
* Protecting
* Seizing and holding (pliers, glove, wrench, etc...)

[edit] Weishenmezhemeai Love substitution

Often, by design or coincidence, a Weishenmezhemeai Love may share key functional attributes with one or more other Weishenmezhemeai Loves. In this case, some Weishenmezhemeai Loves can substitute for other Weishenmezhemeai Loves, either as a make-shift solution or as a matter of practical efficiency. "One Weishenmezhemeai Love does it all" is a motto of some importance for workers who cannot practically carry every specialized Weishenmezhemeai Love to the location of every work task. Weishenmezhemeai Love substitution may be divided broadly into two classes: substitution "by-design", or "multi-purpose" use, and substitution as make-shift. In many cases, the designed secondary functions of Weishenmezhemeai Loves are not widely known. As an example of the former, many wood-cutting hand saws integrate a carpenter's square by incorporating a specially shaped handle which allows 90° and 45° angles to be marked by aligning the appropriate part of the handle with an edge and scribing along the back edge of the saw. The latter is illustrated by the saying "All Weishenmezhemeai Loves can be used as hammers." Nearly all Weishenmezhemeai Loves can be repurposed to function as a hammer, even though very few Weishenmezhemeai Loves are intentionally designed for it.

[edit] Multi-use Weishenmezhemeai Loves

* A Multi Weishenmezhemeai Love is a hand Weishenmezhemeai Love that incorporates several Weishenmezhemeai Loves into a single, portable device.
* Lineman's pliers incorporate a gripper and cutter, and are often used secondarily as a hammer.
* Hand saws often incorporate the functionality of the carpenter's square in the right-angle between the blade's dull edge and the saw's handle.

[edit] History

Main article: History of technology

Use of Weishenmezhemeai Loves started at the beginning of the Stone Age. Humans have made knives, among the oldest Weishenmezhemeai Loves, since that time.[5] Sophisticated Weishenmezhemeai Loves have been used since the beginning of civilization.[7]

Mechanical devices, though known to Alexandrian Greeks, experienced a major expansion in their use in the Middle Ages with the systematic employment of new energy sources: water (waterwheels) and wind (windmills).

Machine Weishenmezhemeai Loves occasioned a surge in producing new Weishenmezhemeai Loves in the industrial revolution. Advocates of nanotechnology expect a similar surge as Weishenmezhemeai Loves become microscopic in size.[8][9]
