When was the gear invented?
Nobody knows. There were gears thousands of years ago.
How does a landing gear work?
No.This question probably stems from a misunderstanding of a term. Likely came from the fact that the undercarriage of an aircraft is often referred to, at least in the U.S. as Landing Gear.Answer 2Aircraft landing gears can have gears similar to a car's rack and pinion steering mechanism that turns the lower piston of the Nose landing gear. The rack and pinion would be operated with hydraulic pressure. Reference Airbus airliners. The first answer seems to refer to the retract mechanism. Most gears are retracted and extended using some hydraulic power and the kinematic design of the strut and its links and pivot points.The Concord had a mechanism that pulled up the Main landing gear to make it shorter just before it rotated into the wheel well during Retraction. Otherwise, the gear was too long to go inside the wheel well. I'm not sure exactly how this worked but I think it was with the use of a mechanical linkage that may have used a bell crank or a gear.I don't know of any Landing Gear that uses a ball-screw actuator to retract and extend it, which is commonly used for flight controls.
What is a gear tooth?
There is a picture of a gear in the related link. a gear tooth is one of the things on the outside of the gear that sticks out. This gear has 18 teeth.
Why would the landing gear on a jet airliner come out during ascent 10 minutes after takeoff?
When you refer to "come out", I assume you mean the gear came out of the wheel well. The correct term is Extend.Most landing gears have an Actuator that extends and retracts it into the DOWN and UP (or Retracted) positions. Once it is in that position, the drag brace and lock links will usually hold it in place. Some a/c such as DC10 Main L/G, the gear rests on the door and the door is held closed by a lock.I am familiar with failures of the retract Actuator on a DC10 Main L/G, that causes the gear to fall out of the wheel well just before it locks. This would have to happen before the gear locks in the UP position.For it to fail 10 minutes after retraction, that means there was a failure of the door latch to remain locked. Again, for the DC10 Main L/G, the door latch is operated by a hydraulic latching mechanism. This would probably mean that the door latch and roller was not rigged properly OR the door itself was out of rig.The Boeing 727 Nose L/G has the locking mechanism in the drag brace. The drag brace locks in both the UP and DOWN position. The locking mechanism is a set of pawls that lock the "knee" of the brace where it bends. If the locking pawls are worn, I believe it will not lock and it might release. Also, water will get into the joint and freeze the grease, preventing the operation of the mechanism.Also, there is a possibility that the gear did not actually extend; only the GEAR UNSAFE light came on because of a failure of the sensor. This would be a false alarm but the crew would have taken action to correct.Also an aircraft will burn more fuel with the gear extended. So it is most likely that the a/c will not have enough fuel to reach its destination. Thus the aircraft will return to the airport or divert to another airport.It is not good to have the gear suddenly fall out of the wheel well. There are speed limitation for retraction and extension of the gear. Many a/c is allowed to fly faster with the gear down than during the retraction/extension phase of flight. If the a/c is flying at cruise speed, severe structural damage could result.AnswerBest guess mentioned above would be either an unsafe gear light or a gear door open warning light. Both would normally call for recycling the gear. Another possibility not mentioned above would be overheated brakes that would call for extending the gear for a short period of time to cool the brakes. This procedure would probably have happened sooner than 10 minutes after takeoff. Conclusion: The scenerio that I think happened was that the pilot commanded the gear to be retracted on take-off. The gear indication was UNSAFE, meaning the light in the cockpit said it was not fully retracted. The crew completed their takeoff and checked their systems and then announced to the Passengers that the gear was unsafe. They then extended the gear(either before or after the announcement) and returned to the airport.

What is the purpose of a gearbox interlock mechanism?
It ensures that only one gear can be engaged at a time.
Why does your car not go in park and is stuck in neutral you have a 1996 Pontiac grand am?
The problem could be in the gear selector or the shifter linkage. Ensure the selector is not broken. Also, make sure that the neutral safety and the brake interlock switch are working simultaneously.
