SIMPLE
MACHINE

One of the most important
reasons why us human
beings had become the
most successful species on
Earth is due to our mastery
of tools and simple
machines.
Simple machines are
tools that make work
easier. It allows the
user to accomplish
more work while
expending less energy

Pulley – consists of a string
or rope wrapped around a
wheel with one end of the
string attached to an object
and the other end attached
to a person or a motor.
A pulley is used to lift
something up specially to
lift the heavy objects. An
effort is a part of pulley
where the force is applied
and the load is the object
which is being applied by
the force exerted.

PULLEY
Examples: window blinds, flagpoles,
zipline, crane

Lever - a device consisting the
fixed movable point called the
fulcrum, a force that lifts the
load called effort and the force
that is being lifted by the effort
called load.
Lever make it
easier to lift
heavy materials,
remove tight
objects and cut
items.

LEVER
Examples: broom, bottle opener,
can opener, seesaw, scissors

Wedge - a double inclined
plane that is sharpened to an
end. It can be used to separate
two objects or portions of an
object, lift an object, or hold
an object in place.
The thinner the
wedge is, the
lesser effort is
needed to cut
objects.

WEDGE
Examples: fork, knife, peeler, nail,
pin, needle

Wheel and Axle – consists of a
round disk, known as a wheel,
with a rod through the center
of it, known as the axle. It is a
type of lever that moves in a
circle around a fulcrum.
It has many uses
in our daily lives.
Cars, pencil
sharpeners, fans,
and in-line skates
all use the wheel
and axle.

WHEEL AND
AXLE
Examples: electric fan, doorknob,
wheelbarrow, pushcart

Inclined Plane – a flat surface
with one end higher than the
other. It allows for heavy objects
to slide up to a higher point
rather than be lifted. It has a
sloping surface used to lift an
object.
Lifting the
object using an
inclined plane
means you use
less force to do
work.

INCLINED
PLANE
Examples: ladder, stairs, slanted
roof, ramp, slide

Screw – a simple machine
with threaded surface and
a point on one end and a
slotted head which holds
or fasten two things
together
The spiral ridges
are referred to as
thread and the
distance each
thread is referred
to as pitch.

SCREW
Examples: jar lid, light bulb,
bottle caps, faucet

What are the
different simple
machines?

It is Maria’s first day in her job
as a saleslady. Her task is to
