Question

The gross weight of a two-place Piper Cherokee is 2000lb and its wing area is 160 ft^2. What is its wing loading

Answer 1

Answer:

$W = 12.5\ lb/ft^2$ --- in $lb/ft^2$

$W = 598.503N/m^2$ --- in $N/m^2$

Explanation:

Given

$Weight=2000lb$

$Area = 160ft^2$

Required

Determine the wing loading (W)

Wing loading is calculated using:

$W = \frac{Weight}{Area}$

Substitute values for Weight and Area

$W = \frac{2000lb}{160ft^2}$

$W = 12.5\ lb/ft^2$

The answer can also be converted to N/m^2

$1\ lb = 4.4482216153N$

$1ft^2 = 0.092903m^2$

So, we have:

$W = \frac{12.5 * 4.4482216153N}{0.092903m^2}$

$W = \frac{55.6027701912N}{0.092903m^2}$

$W = 598.503N/m^2$

Hence, the wing loading is:

$W = 12.5\ lb/ft^2$ --- in $lb/ft^2$

$W = 598.503N/m^2$ --- in $N/m^2$
