At its core, a doorknob uses the circular motion to apply pressure, via a sort of hook, against the latch of the door. This then pulls the latch inwards, allowing the door to open.
yes because when they brake the friction is caused to reduce
Oil is used to reduce friction.
Moving mechanical parts usually need some degree of lubrication so that they do not waste energy in overcoming friction. A very simple case of this would be a door hinge. If the door hinge has too much friction, the door squeaks when you open or close it. It moves smoothly and quietly if it is lubricated. With something like the motor of a car or an airplane, friction would present much more serious problems than the squeak of a door hinge. You would get terrible overheating and eventually an explosion, in an unlubricated motor.
not exactly door hinge does if you say it weird but no not really.
the main reason for doing so is that the surface becomes smooth n in terms of science to reduce "friction" that wud exist between the board n the striker due to which it will move more swiftly with lee deployment of power..!!
One way to reduce friction in a door hinge is to apply lubricant, such as oil or silicone spray, to the moving parts. Regularly cleaning and removing dirt or debris from the hinge can also help reduce friction. Additionally, adjusting the hinge to ensure it is properly aligned and tightened can help prevent unnecessary friction.
To fix a door hinge, you can tighten the screws on the hinge or replace them if they are stripped. You can also lubricate the hinge with oil or grease to reduce friction. If the hinge is damaged, you may need to replace it with a new one.
The friction between oil and a door hinge is called fluid friction. The oil acts as a lubricant, reducing the resistance between the door hinge parts as they move against each other. This type of friction allows for smoother movement of the hinge.
A door hinge typically consists of two plates that are connected by a pin. This design allows for the door to pivot smoothly when opening and closing. Additionally, some door hinges may include ball bearings or washers to reduce friction and wear.
Im Pretty Sure Its Fluid Friction??? ;)

To fix a loose or squeaky door hinge, you can tighten the screws on the hinge with a screwdriver. If the screws are stripped, you may need to replace them with longer or wider screws. You can also lubricate the hinge with WD-40 or a similar lubricant to reduce squeaking.
The pin that slides into a door hinge is called a hinge pin. It is usually removable to allow for door removal or adjustment.
Are the screws on the door hinge stripped?
A hinge door stopper can prevent damage to walls and doors, reduce noise from slamming doors, and improve safety by keeping doors from swinging open too far.
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.
