A simple machine, such as a lever,
that can change the amount of
movement applied to it. A small
motion applied at the end of its arm
will create a greater movement at
the end applied to the load.

- FOLD -
A surface placed at an angle to a
horizontal surface. It makes the
moving of a heavy object from one
level to another possible with less
force than lifting straight up.

- FOLD -
"
A mechanism or simple machine
that multiplies the force applied
to it. It consists of a long arm, to
which the force can be applied, and
a fulcrum (pivot point), on which
the arm rotates.

"
A device or mechanism that change
the amount, speed, or direction
of a force. A machine is also a
framework to which mechanisms
or tools can be attached to make
work more efficient.

machine tool
A machine that make other
machines. Machine tools change
raw materials into parts; these
parts later become machines and
other products.

A basic device that will control or
add power to a tool. Mechanisms are
designed to multiply the force applied
or the distance traveled.

pulley
A small wheel with a grooved rim. A
rope is run through the wheel to lift
weights. Sometimes several of them
are used together to multiply applied
force.

A simple machine in which an
inclined plane is wrapped around a
shaft. A screw is a force multiplier
used to fasten parts.
