You don't have anything following, but an example would be the typical double barreled shotgun.
hinge joints that allow movement in one plane, such as bending and straightening.
kneck.
The theorem emulates the action of a hinge. As the angle of the hinge is increased the distance between the free edges increases.
The elbow is an example of a joint that closely resembles a hinge due to its primarily back-and-forth motion in one plane, similar to a door hinge.
The elbow joint is an example of a hinge joint. It allows movement in only one plane, similar to a door hinge, enabling flexion and extension of the arm.
No, a hinge on a door is not an example of a wedge. A hinge is a type of mechanical bearing that allows for the rotation and movement of a door, while a wedge is a simple machine used to split or lift objects.

No, the Ball and socket joint is in the hand and wrist. An example of a hinge joint is the knee.

There is no "break in" shotgun. A "break open" shotgun is a single barrel, double barrel, or combination rifle/shotgun which breaks open in the sense that a lever will unlock the action, allowing the barrel to pivot at a hinge at the front of the receiver, pivoting the rear of the barrel up to expose the chamber. A shells may be loaded into the chamber and the barrel pivoted back to close the action. The act to "break in" a shotgun means to fire it a few times to loosen it up.
If your elbow were a hinge joint, it would primarily allow for bending and straightening movements in a single plane like a door hinge. However, the elbow joint is actually a more complex joint that allows for flexion, extension, as well as some rotation, making it a modified hinge joint known as a trochlear joint.
