A Z-channel wing spar is constructed using 4 stringers and 3 very thin skin panels.

A Z-channel wing spar is constructed using 4 stringers and 3 very thin skin panels. The cross-section properties of each stringer are (A = 0.4 in2, Iyy = 0.2 in4, Izz = 0.3 in4, Iyz = 0.3 in4). Calculate the Z-channel cross section product of inertia (Iyz) for b = 2.33 inch and h = 2.68 inch. Neglect the skin. (Units: inch^4).

You divide 52 by 50 or \frac{52}{50}
Which is 1\frac{2}{50}
Divide 2 by 50=.04
Now it is 1.04
To change into a percentage, you multiply by 100 since everything compares to 100

1.04ร—100=104โ‡’104%

52 is 104% of 50
