This non profit educational website was started by MIT grad Salman Khan. Let r f r f 92 theta r f be the equation of a polar curve and let 92 theta 92 alpha and 92 theta 92 beta be lines that bound an area enclosed by that polar curve. The polar moment of area can be used to calculate the moment of inertia with arbitrary cross section. e.
