The document discusses the main types of simple machines: wedge, wheel and axle, lever, inclined plane, screw, pulley, and compound machines. It provides examples for each machine, such as knives and scissors for wedges, cars and wheelbarrows for wheel and axles, brooms and screwdrivers for levers, stairs and sidewalk ramps for inclined planes, jar lids and light bulbs for screws, window blinds and garage doors for pulleys, and bikes and garden hoes for compound machines that combine more than one simple machine.

1. Simple Machines
By: Glizyl Luna

2. Wedge
● A wedge is a machine
that pushes materials
apart and cuts things.
● A kitchen knife is a
wedge that cuts food
and it is found in the
kitchen
● A pair of scissors is
also a wedge and it
cuts paper and it can
be found in my pencil
case

3. Wheel and Axle
● The wheel and axle
machines make it easy to
move things by rolling
them and reducing friction.
● A car is a wheel and axle
because it makes it easier
to move people from one
place to another.
● A wheel barrow is a wheel
and axle because it can
move an object easier by
rolling it anywhere.

4. Lever
 Levers are simple machines
that makes lifting weight
easier by using a fulcrum to
redirect force over a long
distance.
 A broom is a lever because
the handle help make it
easier to clean.
 A screw driver is a lever be-
cause the fulcrum is closer
to the load which reduces
the force to screw some-
thing together.

5. Inclined Plane
● An inclined plane is a simple
machine that makes it easier to
move objects upward, but you
have to go further horizontally.
● Stairs are inclined planes
because they make it easier to
go up and down each floor.
● A sidewalk ramp make objects
easier to move and carry heavy
objects out of a truck or car.

6. Screw
● A screw turns rotation into
lengthwise movement and
takes many twist which
holds things together.
● A jar lid is a screw because
it turns and takes many
twist to open and close it.
● A light bulb is a screw
because it has a turning
rotation that takes a twist to
provide light.

7. Pulley
● A pulley makes lifting
things with a rope easier
by redirecting force and
the addition of additional
pulleys.
● The window blind is a
pulley because it helps pull
up the shade.
● The garage door is also a
pulley because it helps lift
the door so cars and other
big objects can go through.

8. Compound Machines
● A compound machine is
combining two or more
simple machines to work
together.
● A bike is a compound
machine because the
wheels of the bike is a
wheel and axle and the
gear shifts and bike
handles are levers.
● A garden hoe is a complex
machine because the
handle is a lever and the
blade is a wedge.
