Real life joints
By: Madeline, Shelby, and Rochelle
BALL & SOCKET JOINT
Shoe laces
Shoe laces fit through the metal rings to keep it in place, however you're still able to move freely in any direction.
Cameras
Cameras are set in place, but not set in position. Much like shoe laces, cameras can move side to side, up and down, and all around.
Wheels
Wheels are another example of a ball and socket because they fit in a socket but still move any direction they need to.
HINGE JOINTS
Trash lid
Lids are a perfect example because they have actual hinge. You can life up a lid and let it close but that's all.
Microwave
Microwave doors have hinges on them too indicating that it can open and close but can not move side to side
Doors
Doors have hinges too. They move along with the hinges but if you try to make it go up and down, it will not budge.
PIVOT JOINTS
Bike tires
When steering a bike, you turn the handlebars to turn left or right which turns the wheel. You can ONLY turn left or right or straight.
Door handle
This handle can stay coward or turn up or down. The handle can not make a full 365 turn.
Faucet handle
This handle to turn on the gas can stay as it is or turn but not all the way around, indicating that it's a pivot joint.
GLIDING JOINTS
Drawers
Drawers are a gliding joint because you can slide them in and out.
Elevators
Elevator doors slide open and closed on a track keeping interim moving anywhere else.
Sliding doors
These are another perfect example that shows how the doors will move from side to side but can not go forward and backward or up or down.
