The force of gravity is not the same everywhere on Earth. It is slightly weaker at the equator due to the centrifugal force caused by Earth's rotation and the fact that the Earth is not a perfect sphere but an oblate spheroid. Gravity is stronger at the poles and weaker at higher altitu...

Several B-377s had encountered trouble due to a runaway or “overspeeding” propeller, a potentially catastrophic situation in which the variable-pitch prop cannot be feathered, and centrifugal force wrenches the blades to the lowest pitch stop. The resulting drag makes the aircraft aerodynamically...
Twenty-five years before the Malaysia Airlines mystery, one of the most dramatic events in aviation unfolded in the skies over Iowa as heroic pilots battled to land a crippled DC-10.
The centrifugal force is dependent on the rate of rotation and the distance from the spin center and the aircraft center of gravity. The rudder is the only control surface that can counter act this force and stop the rotation. At some point as the CG moves aft the rudder will be unable ...
A direct current motor (DC motor) is an electric motor that operates on direct current. The operation of an electric motor is based on basic electromagnetism. When a current-carrying conductor is put in an external magnetic field, it will feel a force that is equal to the current in the ...
If you've ever looked at a Formula One car, an Indy car or a Champ car, you know that a big part of the car's body is the aerodynamics package. At the front and back are wings. However, these wings are mounted upside down. Their purpose isn't providing lift, like the wings of...
