Answer:
Quantity B is greater.
Explanation:
<u>Given</u>:
(x -2y)(x +2y) = 4
A = x² -4y²
B = 8
<u>Find</u>:
the relationship between A and B
<u>Solution</u>:
The given expression can be expanded to give ...
x(x +2y) -2y(x +2y) = x² +2xy -2xy -4y² = x² -4y²
This is precisely the expression designated as A. Its value is 4.
4 < 8
A < B
Quantity B is greater.
Wing D (high camber and surface area, least weight) generated the most lift force and Wing C (most streamlined) generated the least drag force. It is concluded that the shape of a wing does affect the lift and drag of an airplane.
Answer:
given d= 10.2x10-3m
change in diameter d' =3.4x10-6 m
elastic modulus=207x109pa
1/m=0.30
we know that stress/strain=E
but poissons ratio 1/m = lateral starin/longitudinal starin
0.3= (d'/d)/(L'/L)
L'/L = 3.4x10-6/(0.3x10.2x10-3)
= 1.11*10-3
E= (f/A)/(L'/L)
force f= E*A*(L'/L)
f =(1.11*10-3)*207*109*(3.1415*(10.2*10-3)2)/4
= 18775.2N =18.775KN
Explanation:
The force that produce an elastic reduction is 18.775KN
