A group of two or more gear wheels is commonly referred to as a "gear train." Gear trains are used to transmit torque and rotational motion between different gears, allowing for changes in speed, direction, and force. They play a crucial role in various mechanical systems, from simple clocks to complex machinery. By engaging with one another, the gears work together to achieve desired mechanical advantages.

A space shuttle has a total of 12 wheels. This includes the main landing gear, which consists of two main wheels on each of the two main gear assemblies, and a nose gear with two additional wheels. The shuttle uses these wheels for landing and taxiing on runways after re-entry to Earth's atmosphere.
It doesn't have a tail wheel nor does it have a tail skid. It has two wheels on the nose gear two wing gear with 4 wheels each and 2 body gear with 4 wheels each
3 sets of two tires. Two rear landing gear and one front landing gear.
A Boeing 767 aircraft has a total of 10 wheels. Two on the front landing gear, 4 on each of the two main landing gear.
6. There are two mains, both with two wheels, and two on the nose gear.
They weren't 'invented' - a gear ratio is simply the difference in the number of teeth on two connected gear wheels.
An Airbus A320 aircraft typically has six wheels. It features a main landing gear that consists of two main gear assemblies, each with two wheels, and a nose gear assembly with one wheel. This configuration helps ensure stability and support during takeoff, landing, and taxiing.
A Boeing 737 aircraft has a total of 6 wheels. Two wheels on the front landing gear and two on each of the two main landing gears.Four (4) on the main gears (2 LH and 2 RH)Two (2) on the nose gearTotal six (6)The Boeing 737 has a total of 6 wheels - 4 for the main undercarriage landing gear (consisting of two 2 wheel bogies) and 2 for the nose landing gear.
The Boeing 747 has a total of 16 wheels: four main landing gear wheels on each side and two nose landing gear wheels at the front. The main landing gear wheels typically have a diameter of about 25 inches (63.5 cm), while the nose gear wheels are slightly smaller, with a diameter of approximately 20 inches (50.8 cm). These large wheels are designed to support the aircraft's weight during takeoff, landing, and ground operations.
