SIMPLE MACHINES

TRACY HANAOKA

WEDGE: THUMBTACK Used to push between something, in this case, it’s WEDGING itself into the poster, and

then into the corkboard to hold the poster in place on my wall. Picture taken: In my room

WEDGE: KNIFEThe knife slices through foods “wedging” itself to cut things

Picture taken: Kitchen

WHEEL&AXEL: BIKE WHEELThe bike wheel is used to mobilize the bicycle by turning on its axel with help from the pedals.

Picture taken: In my backroom

WHEEL&AXEL: CAR WHEELSThe car wheels help to mobilize the car when the gas pedal is pressed

Picture taken: Outside my house

LEVER: DOORKNOB A doorknob is a lever. Your elbow is the fulcrum. Doorknobs are an easy way to open

doors without much pushing and pulling.

INCLINE PLANE: CAGE DOORInstead of making a big leap out of the cage which is pretty tall, Mr. Bun-Bun uses the

incline plane of the cage door to hop down. Picture taken: Living room

SCREW: GLUEThe bottom part of the glue stick is used to screw upwards to press the glue further up as

it starts to get smaller. Picture taken: Kitchen

SCREW: BOTTLEScrew tops on bottles are very common. They help to keep dust/dirt/etc. out and keep

carbonation in sodas and keep water fresh.

PULLEY: WINDOW SHADESA pulley is used here to make closing the shades easier. Instead of climbing up to lower

or heighten the shades, there is a mini pulley system with a string that allows us to tug on it and raise/lower the shade with ease

PULLEY: BLINDSThere is a non-visible pulley system in the blinds on my window. It’s like a quick release system that doesn’t need strings. All you do is gently tug on the blinds and it will raise

and lower itself Picture taken: Front room

COMPOUND MACHINE: STAPLERInside of a stapler is a lever and a wedge. The lever (stapler handle) is used manually by pressing

down on it with force. The wedge (staple) then pokes through the paper. Picture taken: Kitchen

COMPOUND MACHINE: SCISSORSScissors combine a screw and a lever. The screw is used to hold the parts in place, while your hand is the force that pushes the scissors together to cut through paper. I guess it could also be a wedge

because it slices THROUGH the paper or whatever else you use to cut.
