Equipment
- Also know as tools. The most basic tools 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.
Philosophers once thought that only humans used tools,
and often defined humans as tool-using animals. But
observation has confirmed that monkeys, apes and other
animals, mostly primates, but also some birds (ravens,
for instance), and sea otters can use tools as well.
Later, philosophers thought that only humans had the
ability to make tools, until zoologists observed birds[1]
and monkeys[2][3][4] making tools. Most anthropologists
believe that the use of tools was an important step
in the evolution of mankind. Humans evolved an opposable
thumb (useful to hold the tools) and an increase in
intelligence (aiding in the use of tools).
Most tools can also serve as weapons, such as the
hammer and the knife. Similarly, people can use weapons,
such as explosives, as tools. |
