Question

The aspect ratio is used when calculating the aerodynamic efficiency of the wing of a plane. For a standard wing area, the

5²
function A(s)
36 can be used to find the aspect ratio depending on the wingspan in feet.
If one glider has an aspect ratio of 5.7, which system of equations and solution can be used to represent the wingspan of
the glider? Round solution to the nearest tenth if necessary.

Answer 1

Y=s^2/36 and y=5.7;14.3 ft

Explanation:

A(s)=s2/36 is the function. A(s) is the aspect ratio, while s is the wingspan. A(s) = 5.7 if one glider has an aspect ratio of 5.7. We'd want to know the glider's wingspan. By replacing A(s) with Y, we get the following equation system:

• Y=s^2/36
• with y = 5.7
• 5.7 = s^2/36
• 5.7*36 = s^2
• √205.2 = s
• 14.3 ft
