Define a python function to determine the 2nd moment of area I, under the parabola, with respect to the centroidal-axis. The
parabolic curve is defined as z = ky2, where k = b/h². The centroidal axis has a given distance d with respect to z axis.
Hints: Use the parallel axis theorem. Find the 2nd moment of area against z axis first and then use the formula I₂ = I₁ + d²A to
calculate I, where d is a given value (no need to derive). Note that this question requires you to derive the equation first.

The parabolic curve is defined as z = ky2, where k = b/h². The centroidal axis has a given distance d with respect to z axis. Hints: Use the parallel axis theorem. Find the 2nd moment of area against z axis first and then use the formula I₂ = I₁ + d²A to calculate I, where d is a given value (no need to derive).
