The weights .of the sides will be proportional totheir lengths, and may be representedby them. Let it first be required tofind the… … oo oc :: CD : AB+BO; then will o be the centre of gravity of the three sides,AB^ B (7, and OD. Join o with d, and proceed as before,conthiuing the operation till the last point, 6r, is found; thiswill be the centre of gravity of the perimeter. To find the centre of gravity of the area, divide it…
