CALCULATION OF CENTROID
PROCEDURE TO FIND CENTROID OF COMPOSITE AREAS AND LINES
Following steps are adopted to find co-ordinates of centroid of composite figures:
1) Select suitable co-ordinate axes if not given.
2) Divide given area/lines in to different parts having known area or length and known centriodal distances.
3) Check Symmetry of Figures
(a) If section is symmetrical about x axis we can find y directly without any calculations.
(b) If section is symmetrical about y axis we can find x directly without any calculation.
