AERO 1010 TEST 2 ACTUAL EXAM
QUESTIONS AND CORRECT DETAILED
, Four Forces of Flight - ANSWERlift, weight, thrust, drag
Bernoulli's Principle - ANSWERAs velocity of a fluid increases, the pressure exerted
decreases.
Newton's 3rd Law - ANSWERFor every action, there is an equal and opposite reaction.
Explain the theory of lift. - ANSWERAir on top of airfoil is moving at a higher speed than
the air below, so the air below exerts a greater pressure, which lifts the aircraft.
How does the theory of lift relate to to the camber of a wing? - ANSWERAirflow bending
around a camber exerts a downwash. This downwash strikes the bottom of the wing
and produces lift.
Laminar flow definition - ANSWERsmooth airflow over the wing
Transition point definition - ANSWERpoint at which the boundary layer changes from
laminar to turbulent
Turbulent flow definition - ANSWERchaotic changes in pressure and flow velocity
Boundary layer definition - ANSWERthin layer near the surface where the velocity
changes from zero at the surface to the free stream value away from the surface
What is a stall? - ANSWERAngle of attack where there is no air flowing over the wings,
and, therefore, no lift being generated
Standard pressure and temperature - ANSWER29.92" Hg at 15 degrees Celsius
Standard pressure lapse rate - ANSWERlose 1" Hg for every 1000 ft
Standard temperature lapse rate - ANSWERlose 2 degrees Celsius for every 1000 ft
Main component of the airplane - ANSWERfuselage
Tail section of the airplane - ANSWERempennage
What is included in the empennage? - ANSWERElevator, rudder, horizontal and vertical
stabilizers
The ___ is located on the vertical stabilizer. - ANSWERRudder
