Avit 323 Exam 1 UPDATED ACTUAL Exam
Questions and CORRECT Answers
Newton's First Law - CORRECT ANSWER - An object at rest stays at rest and an object
in motion stays in motion with the same speed and in the same direction unless acted upon by an
unbalanced force.
Newton's Second Law - CORRECT ANSWER - Force = mass x acceleration
Newton's Third Law - CORRECT ANSWER - For every action there is an equal and
opposite reaction
Magnus effect - CORRECT ANSWER - Deviation in the trajectory of a spinning object
toward the direction of spin (Ping Pong Ball)
Bernoulli's Principle - CORRECT ANSWER - as the velocity of a fluid increases, the
pressure exerted by the fluid decreases
As Static pressure increases Dynamic Pressure decreases
Planform - CORRECT ANSWER - the shape of the wing viewed from above
What is work? - CORRECT ANSWER - the product of force and distance
What is power? - CORRECT ANSWER - the rate at which work is done
On the Graph what does the X-axis represent? - CORRECT ANSWER - AOA
On the Graph what does the Y- axis represent? - CORRECT ANSWER - Coefficient of
Lift
, Total Energy= what - CORRECT ANSWER - Potential + Kinetic
What is standard pressure at sea level - CORRECT ANSWER - •14.7 Pounds per square
inch (PSI)
•1,013.2 millibars (mb)
•29.92 inches of mercury (Hg)
What is the average rate of pressure change in the atmosphere? - CORRECT ANSWER --
Decreases approximately 1" (Hg) per 1,000ft up to 10,000ft.
Scalor - CORRECT ANSWER - A quantity with only magnitude
Vector - CORRECT ANSWER - A quantity that has magnitude and direction
Moment(torque) - CORRECT ANSWER - Force x distance from the center of mass
(ARM)
standard temp at sea level - CORRECT ANSWER - 15 C
How much does temp decrease with altitude - CORRECT ANSWER - 2 C every thousand
feet
What is a stall? - CORRECT ANSWER - Exceeding the critical angle of attack
Stall Equation - CORRECT ANSWER - its the L= (oV^2/295)x Cl x S
o is the density ratio
V is velocity
