Each control surface on an aircraft has a hinge of some sort. By moving the control, there is an aerodynamic moment about the hinge. The pilot must provide the moment (force)to counter that hinge moment. The feedback of
this required force to the pilot is an additional cue to help him to fly the aircraft.
A block hour is the time from the moment the aircraft door closes at departure until the moment the aircraft door opens at the arrival gate following its landing.
There is a transponder in every plane which gives signal where the plane is going.

It is easier to push open a door from the farthest distance from the hinge because this position provides a greater mechanical advantage or leverage. This creates a larger moment arm, reducing the amount of force required to overcome the resistance of the door.
To fix a door hinge that is not working properly, you can try tightening the screws on the hinge, lubricating the hinge with oil or WD-40, or replacing the hinge if it is damaged.
It is a beam that is attached at aboundary that is free to rotate, like a hinge. It cannot develop a bending moment. It is often used to idealize a simply supported beam
A hinge joint is not immovable. A hinge joint has one plane of motion. A good illustration of a hinge joint is the knee joint.

To replace the Ford Explorer rear window hinge, you have to buy a similar window hinge. Use a screwdriver to open the hinge and replace the hinge but fitting it in the window.
To fix a storm door hinge that is not working properly, you can try tightening the screws on the hinge, lubricating the hinge with oil or silicone spray, or replacing the hinge if it is damaged.
