i am sure that it is liquid friction trust me i am a science teacher
The friction on a hinge needs to be small at the pivot point where the hinge rotates. This allows smooth movement and prevents the hinge from sticking or getting stuck. However, in other parts of the hinge, such as the pins or brackets, a small amount of friction may be desirable to provide stability and prevent excessive movement.
Friction is the force that opposes the motion. It is the force between two surfaces rubbing together. Actually there are three kinds of friction:static friction - friction occurs at rest. It is also the strongest type of friction.kinetic friction - friction that occurs when an object is in motion.rolling friction - the weakest of all the three.So that's the basic definition of friction and its kind.add Commonly, the status of the friction alternates between static and sliding many times per second. Commonly called 'slip stick' friction. This is the cause of a squeaky door hinge, the crunch of snow, and even if some remarkable 'singing sands' in some deserts.[Alongside a squeaky door hinge you'll often find a deposit of fine dark powder - this is iron dust - some of the iron actually torn off the hinge surface in moving between these two frictions. ]
It means what how can the friction be reduced. To answer this question, Friction can be reduced by devices like ball bearings, wheels and lubricants.
No.
Im Pretty Sure Its Fluid Friction??? ;)

efficency is reduced by friction.

Bro, DOOR-HINGE. Door-hinge rhymes with Orange.

The very easiest way is this: # Remove the middle hinge pin. (bottom hinge pin if you only have two hinges) # Set it on a concrete sidewalk, driveway etc. laying flat. # Hit it with a hammer in the middle. This will bend the pin slightly, causing friction in the hinge and, once put back in the hinge, it should hold the door in any position you open it to.
A door which hangs on hinges. The hinge is what allows a door to open and close and is made of metal, attached to the door by bolts or screws.
The hinge of the door is loose.
because it works like a door hinge. When the door hinge is opened wider the angle is greater and when opened less the angle would be lesser.
