Once upon a time there was a man named Billy
Bob Joe. He always had trouble doing work. One
day he went up to his boss and asked, “ I need
something to make my work easier.”
The boss answered and said, “Why don’t you
use Simple Machines?” “What are Simple
Machines?” asked Billy Bob Joe. “Well Billy,
Simple Machines are Machines that makes
things easier.” “Let me explain to you the
different types of Simple Machines.”
“One type of Simple Machine is called a lever.”
said the boss. “A lever is a strong bar that turns
on a fulcrum.” “What is a fulcrum?” asked Billy
Bob Joe. “A fulcrum is any support under a
lever.” “Levers are used to measure the weights
of two things if they are equal or not.”
“Examples of levers are your leg, a gate and
broom.”
“Another Simple Machine is called a pulley.” “A
pulley is used to lift weights or things to another
place using a belt or a rope.” “A rope fits into a
socket allowing it to pull up objects heavy or
light like the American flag.
“Another Simple Machine is a Wheel and Axle.”
“A wheel and axle is a Simple Machine that
allows you to turn something or it turns itself
around an axle.” “An example of a wheel and
axle is a doorknob.” “A doorknob turns around
an axle and the knob is the wheel.”
“Another simple machine is called a Gear.” “A
Gear has teeth like ends that fit into other
Gears.” “For example a clock has gears in it to
make it tick.” “The ticking is caused by the mini
Gears moving at a speed.”
“Another Simple Machine is called an Inclined
Plane.” “An inclined plane can help push boxes
into a truck.” “Inclined planes can also be fan
blades which cut into the wind making cold air.”
“Another Simple Machine is called a Wedge.” “ A
wedge fits between two things and splits them
apart.” “An example of a wedge is a knife.” “A
knife slices cheese or steak apart by wedging
into them.”
“The last Simple Machine is a Screw.” “A screw is
a Simple Machine that holds things together.”
“For example if you take out all of the screws in
your toy car then it will fall apart.”
“That is all the Simple Machines Billy” “But I
have one more thing to tell you.” “This one is
called work.” “Work is the effort you put into
moving something to another place.
“Thank you so much boss” said Billy Bob Joe.
Well Billy Bob Joe was not done and he knew
that. He used all of his new Simple Machines
that he learned about and got his work done
faster. In fact he did it so fast he got a raise and a
promotion! So Billy Bob Joe started to love
Simple Machines and he loved them now and
forever.
