Examples of Levers

Examples of Levers
There are many levers that we use; at home, at school,
at the park, at work. Can you think of some examples?
Take a look…
Many of the following levers have been combined with
another simple machine to make a useful tool or piece
of equipment.
An axe’s handle is a lever.
The cutting part is a wedge!
A baseball bat is a lever. The
effort is created when you
hold the bat (and eventually
swing it). The fulcrum is at
the tip of the handle. Using
your wrists, you can pivot and swing the bat. The load
occurs at the tip of the bat where it meets the ball.
Can you show where the effort, load and fulcrum are?

baseball bat.

A teeter totter is a lever. It rests on a support, (or
pivot point) which is the fulcrum. The person on the
ground (Linus) is the load; ihe needs to be lifted up.
To get him up into the air, Charlie Brown will exert an
effort or force downward. Once Linus is up in the air,
Charlie Brown becomes the load and it’s then Linus’
turn to exert an effort or force. This constant
imbalance is what all the fun is about!mbala

principle or idea as

He shoots! He
scores! What a
lever! Yes! A hockey
stick is a lever. In fact,
it’s a special lever that
allows the player to
change the amount of
effort and the direction of the load! When you hold the
stick, you are preparing for the effort. The top of the handle
is the fulcrum. And of course, the blade of the stick is the
load…the part of the stick that is designed to touch the puck!
A stapler is a lever. It has an important job to do at
the office or at school.
Can you guess where the fulcrum, effort and load
are?
