Is there any benefit for a pilot to see acceleration relative to a rotational reference frame... that is rotating at the same velocity as the airplane?! Meaning zero acceleration. To me it seems at least useless and just wrong, in some way.
How do you know which forces the airplane is...
Hi,
I've seen the forces in a turn depicted two different ways:

Which one is correct?
I think the first one would be since it's...
So if the graph is translated left or right, I can still say that "changes in y are proportional to changes in x" but I can't say "y is proportional to x" - is that correct?
Quote from Wikipedia:
I've been told by people that a graph with a straight line on it can be proportional but only if it passes through the origin. I fail to see why that's true. If a translation was applied and it was moved 1 unit to the right then, all of a sudden, x is not proportional to...
I have a question based on this little diagram I whipped up!

Will the 25 PSI (generated by a pump) applied to the curved surface on the bottom of the piston exert a higher force upwards to oppose the downward force on top of the piston?
A detailed...
Hi.. I'm a pilot and I'm trying to get a better grasp on meteorology. I'm wondering how exactly water vapor is contained in air. I understand it's mostly governed by the temperature of the air but does the temperature of the water affect that? Why is it dependent on the temperature of the air...
