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

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

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

Step-by-step explanation:

Given

`Weight=2000lb`

`Area = 160ft^2`

Required

Determine the wing loading (W)

Wing loading is calculated using:

`W = (Weight)/(Area)`

Substitute values for Weight and Area

`W = (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 = (12.5 * 4.4482216153N)/(0.092903m^2)`

`W = (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`
