Calculating the Second Moment of Area

The General Formula

Every so often in maths, a formula with enormous potential comes along. These formulae amass powers beyond the imagination of normal expressions until they become all consuming. As they develop they tend to give birth to hundreds of new, more specific formulae. These fearsome combinations of letters and numbers are known as.... GENERAL FORMULAE.

Using the general formula and some funky maths it is possible to derive the equations to calculate the second moment of area of specific shapes. The videos below show some of these derivations.
