ABOUT THE TOPIC

You can use a machine to transform energy,
transfer energy, multiply speed, multiply force, or
change the direction of a force so you can

accomplish work more quickly, easily, or both. A
simple machine is a device that does work with only
one movement.

GUIDE CARD

THE BIG PICTURE

Simple Machines are basic mechanical devices
for applying a force and doing work. More complex
machines are made up of a bunch of simple
machines.

There are 6 basic types of simple machines:

Lever

The lever is made up of a https://image.freepik.com/free -vector/flat -
straight rigid object like a board or a bar engineering -team -work_23 -2148187675.jpg

which pivots on a turning point called a fulcrum. Levers make

work easier by using leverage which multiplies the force. When

you use a lever, you move a smaller force a longer distance to

lift a load a short distance. Examples of levers include a

seesaw, pliers, crowbars, and tweezers.

Wheel and axle
The wheel and axle is another simple machine. It uses

a wheel with a rod attached in the middle as
an axle to help it to lift or move loads. In
some cases, this machine works like a lever to
multiply force (like with a doorknob or a fishing reel). In other
cases, it is used to move objects easier such as with wheels on a bicycle.

Pulley
Pulley is a type of simple machine that uses a wheel with a groove
in it and a rope. The rope fits into the groove and one end of the
rope goes around the load. You pull on the other end. The pulley
helps you to move the load or change direction of the force.

Some examples of pulleys include cranes, flag poles, and window blinds.
When multiple pulleys are used together it's called a block and tackle. Another
use of the pulley is with a flat wheel and belts. These kinds of pulleys are often
used in cars.

Inclined plane

An inclined plane is a flat surface with one
end higher than the other. This allows for heavy
objects to slide up to a higher point rather than be
lifted. It is generally easier to slide something than to lift it.
Examples of inclined planes include slides and ramps.

172/

Wedge
If you put two inclined planes back to back, you get a

wedge. A wedge is a simple machine used to push two
objects apart.
Examples of the wedge include knives, chisels, and
axes.

Screw
A screw is a special kind of inclined plane. It's basically an

inclined plane wrapped around a pole. Screws can be used
to lift things or to hold them together.
Examples of the screw simple machine include swivel
chairs, jar lids, and, of course, screws.

DID YOU KNOW?

L

The wheel and axle is a special kind of lever. It’s a
rotating lever that turns 360 degrees around a fulcrum.

SCIE-TEXT

Mechanical Advantage (MA) of a machine is the ratio of
the force on a load to the force of effort. The greater the
MA, the greater the machine at multiplying effort.

Pulley is a grooved wheel combined with a rope that allows you to raise, lower,
or move a load.
Screw is a special kind of inclined plane. It's basically an inclined plane wrapped
around a pole. Screws can be used to lift things or to hold them together.
