So yyou have a bigger leaver to open the door with. The width of the door acts as a lever.
It is easier to push open a door using the knob because the knob is located further away from the hinge, which means the force from pushing is applied farther from the rotation point (hinge), resulting in less resistance. Additionally, the design of the knob allows for a better grip, making it easier to apply force effectively.
it is easier to open a door using the handle, opening from the hinges is much more difficult... FACT
A door opens more slowly when pushed closer to the hinges because the force applied is farther away from the pivot point, making it harder to overcome the resistance of the hinges.
To open a door when pushing on it perpendicularly, stand facing the door and use your hand to push on the side of the door that is farthest away from the hinges. This will allow the door to swing open easily.
If we apply oil on door hinges, the friction will decrease because the oil acts as a lubricant, reducing resistance between the moving parts. This will make it easier to open and close the door smoothly.
To determine the direction in which a door swings, stand facing the door. If the hinges are on the left side, the door swings open to the left. If the hinges are on the right side, the door swings open to the right.
A door on hinges is an example of a lever. The hinge acts as the fulcrum, allowing the door to pivot open or closed.
The direction a swing door should open depends on the location of the hinges. If the hinges are on the right side, it is a right-hand swing door. If the hinges are on the left side, it is a left-hand swing door.
One way is to remove it from its hinges or mounting.
The door-handle is usually on the opposite side of the door from the hinges to give the best leverage on the door, ie you need less force to pull the door open. You are producing a torque on the door. (Torque is a rotational force). Essentially, as you apply a force to rotate something, less is needed to cause rotation if you apply that force further away from the center of the rotation (in this case, the hinges). Try to push open a door by pushing on the door very close to the hinges, and you will find that it is quite difficult.
Open the door, pull the pin from the stopper between the two hinges and undo the four bolts on the hinges, thats it
Take it into Mazda or use a crowbar.
