mean center line- - ANSWERSRelative Wind: E
Chordline: B
Leading Edge: A
Trailing Edge: D
Mean Center Line: C
What is the difference between an airfoil section and a wing's planform - ANSWERSThe
airfoil section is the difference between the pressure on the upper and lower camber
and it a slice of the wing whereas the wing's planform is a view of the wing from above.
What is the difference between the "mean camber line" and the "chord line" of a wing
section? - ANSWERSThe chord line is a straight line from the leading edge to the
trailing edge and the mean chamber line is a line from the leading edge to the trailing
edge that cuts the airfoil into two equal sections
What are two characteristics of a Laminar Flow Boundary Layer? - ANSWERSTwo
characteristics of the laminar flow boundary layer are normal streamline and the airflow
not mixing
Calculate the potential energy of an Acher weighing 2,500 pounds if it is at an altitude of
0.5 feet above the ground. Answer only numerically. - ANSWERS1250 lbs
What is the law of conservation of energy - ANSWERSThe law of conservation of
energy is that energy cannot be destroyed or created but can be transferred between
different forms.
The amount of yawing moment that the rudder can generate is affected by which two
factors? - ANSWERSAerodynamic force / Distance from C.G. to rudder
A 100 lb. weight is dropped from a height of 20 feet. What is the Ep before it is
dropped? - ANSWERS2,000 ft-lbs
What is the kinectic energy of this same weight ( 100 lbs ) at the moment of impact
(after falling 20 feet) - ANSWERS2,000 ft-lbs
