The weight of the North American P-51 Mustang airplane is 10,100 lb and its wing platform area is 233 ft2 . Calculate the wing l
Natali5045456 [20]

Answer

given,

weight of airplane,W = 10,100 lb

Wing area,A = 233 ft²

now,

Wing Loading Calculation in English engineering

        = \dfrac{W}{A}

        = \dfrac{10,100}{233}

        = 43.35 lb/ft²

Wing Loading in SI unit

        = 43.35\times \dfrac{4.448\ N}{1\ lb}\times (\dfrac{1\ ft}{0.3048})^2

        = 2075.51\ N/m^2

Wing loading in kgf/m²

      = \dfrac{2075.51}{9.81}

      = 211.57 kgf/m²

In the sum of 54.34 and 45.66, the number of significant figure for the<br>answer is​
Natali5045456 [20]

Answer:

5

Explanation:

54.34+45.66=100.00 (you have to use the .00 because when you add to numbers you keep the number of decimals)

so you get 100.00

all numbers that are not 0 are sig figs so 1 is a sig fig

If a number ends with a 0 after a decimal place that 0 is a sig fig

all numbers between two sig figs are sig figs so that would make all of the numbers sig figs
