Learning Objectives
 Describe the functions of simple machines.
 Describe the functions, parts, and types of
levers.
 Cite examples of the different types of levers.

Simple Machines
Simple machines
make it easier for us
to perform work and
other activities.

Simple Machines
 transfer force from one place to another
change the direction of the force
increase the magnitude of the force exerted
increase the distance from which force is applied

Simple Machines
Lever Pulley Inclined Plane
Wedge Screw Wheel and Axle

Lever
A lever has a long, stiff
beam or bar resting, and a
fulcrum.
It is used to carry or lift
heavy objects easily.

Parts of a Lever
A lever consists of three main: the fulcrum, the load, and the effort.

Parts of a Lever
The fulcrum is
where the rod or
beam pivots.
The load refers to
the weight carried
by a lever.
The effort is the
force applied to
do the action.

Types Class
Lever
First Class Lever
The fulcrum is
located between the
load and effort.

Types Class
Lever
Second Class Lever
The load is positioned
between the fulcrum and
the effort.

Types Class
Lever
Third Class Lever
The effort is at the middle
of the load and the
fulcrum, which are at the
opposite ends of the
beam.

Summary
Simple machines are objects that make activities
and work easier for us. An example of this is the
lever.
Lever: Use
---- used to carry or lift heavy objects easily
Lever: Parts
---- the fulcrum, the load, and the effort.
Lever: Types
---- First class, second class, third class
