Calculate the second moment of area (also known as moment of inertia of plane area, area moment of inertia, or second area moment) and the section modulus of a profile with elliptical cross section, width *A* and height *B*. Use this to calculate deflection or stress in a loaded profile.

\( I_{yy}=\dfrac {\pi AB^{3}} {64} \)

\( W_{yy}=\dfrac {\pi AB^{2}} {32} \)
