On the other hand, the large wheel is heavier, and suffers more from air resistance than the small wheel.
This element of air resistance must be taken into consideration in determining the engine horsepower required.
air resistance against a machine turning becomes greater, it slows down the speed, decreases the lifting power of the planes.
Their hulls, motor gondolas, in fact, all braces and wires were streamlined so as to offer the least air resistance.
With any gravity or air resistance at all, the Italian couldn't have carried even one.
The air resistance produced by the cables is therefore very slight, since only two lines are exposed.
The air resistance of different models is accurately determined.
Only when it was up where air resistance was a very small fraction of ground-level drag would its own rockets fire.
We are up high enough to make the air resistance almost nothing, even at this velocity, but we still require some power.
The range was almost point-blank, and there was, of course, no need to take either gravity or air resistance into account.
