I have a PS4 but I have to download it
Answer:
A. -0.003
B. 0.02
Explanation:
<u>Step 1:</u> identify the given parameters
Giving the following parameters
Wing area (S)= 1.5 m²
Wing chord (C) = 0.45 m
Velocity (V) = 100 m/s
moment about center of gravity(Mcg) = -12.4 N-m
at another angle of attack, L = 3675 N and Mcg = 20.67 N-m
<u>Step 2:</u> calculate the value of the moment coefficient about the aerodynamic center (Cmcg)
= 6125 N/m²
= -0.003
at zero lift
<u>Step 3</u>: calculate coefficient of lift
Cl = L/q*s
Cl = 3675/6125*1.5 = 0.4
<u>Step 4:</u> calculate the location of the aerodynamic center
New moment coefficient about the aerodynamic center (Cmcg):
= 0.005
=0.02
the location of the aerodynamic center = 0.02
Answer:
D. Fire clay bricks
Explanation:
Just like in the steel mills with the big furnaces that's what causes all the smoke to come out of the stacks
