Somebody said, if the normal capacity of a motor bike engine is to run at 40 Km/hr, is then fitted to a boat it can sail at 80 km/hr, if you use the same engine to an aircraft it will fly more than that. The frictional force is what reduces the capacity of an engine. (Theory of Newton
, Buoyancy
, Bernoulli
says that).
(Experts may advice.)
Now I am looking the same in different way:
(1) A motor bike / Vehicle has got one axis freedom (say x axis) – they have to follow the road. So person diving
it called as “Driver”.
(2) A motor boat has got two axis freedoms; ( X axis & Y axis) can sail on a big flat water surface, and 70% of
earth is water, So person sailing it is called “Captain”.
(3) An aircraft has got 3 axis freedoms, ( X axis,Y axis & Z axis) can fly in a space of air around earth (100%),
person flying is called “Pilot”
But the toughest along all is 3 axis freedoms is without oxygen.
(1) Space crafts – Astronaut
(2) Submarine – Helm and Planesman, submarine Captain.
