Lever principle of claw hammer:
When the lever is used, in order to save power, the lever should be used when
the power arm is longer than the resistance arm. If you want to save distance,
you should use a lever with the power arm shorter than the resistance arm.
Therefore, the use of the lever can save effort, can also save distance. But to
save effort, you have to move more distances. If you want to move less, you have
to work harder. It is impossible to move with less effort and less distance. It
is from these axioms that, on the basis of the "center of gravity" theory,
Archimedes discovered the lever principle, that is, "when two weights are
balanced, their distance from the fulcrum is inversely proportional to the
weight.
