AVIT 323 Block 9 Exam Questions &
Answers 100% Solved!
Airfoil Section - ANSWERScross-sectional shape of the wing
Planform - ANSWERSthe shape of the wing viewed from above
Chordline - ANSWERSan infinite straight line drawn through the leading and trailing
edges of an airfoil
Leading Edge - ANSWERSthe forward edge of the wing
Trailing Edge - ANSWERSthe rear edge of a wing
Aspect Ratio - ANSWERSspan divided by average chord
Newton's Laws of Motion - ANSWERS1. an object at rest will remain at rest unless
acted upon by an (unbalanced) force, and an object in motion will continue to stay in
motion with the same speed and in the same direction unless acted upon by an
(unbalanced outside force) which is also called "inertia"
2. acceleration is produced when a force acts on mass and the greater the mass of the
object being accelerated, the greater the amount of force needed to accelerate that
object (F = M x A)
3. for every action, there is an equal and opposite reaction
Conservation of Mass - ANSWERSthe principle stating that matter is not created or
destroyed during a chemical reaction
Mean Camber Line - ANSWERSan imaginary line between the leading and trailing
edges and halfway between the airfoil's upper (curved) and lower (flat) surfaces
Camber (Upper and Lower) - ANSWERSthe convexity of the curve of an aerofoil from
the leading edge to the trailing edge
Symmetrical Airfoil - ANSWERSupper and lower surfaces are mirror images which
leads to the mean camber line to be coincident with the chord line
Cambered Airfoil - ANSWERSmean camber line will be above the chord line
Conservation of Energy - ANSWERS1. the total energy of a system remains constant
2. energy cannot be created nor destroyed
3. energy can only change between different forms
