Draw CE and DF per-pendicular to AB; join EO and FO cutting CD in H and K. In thesimilar triangles OHK and OEF,… … O X I !■. L35. Graphical method for finding the centre of gravity of a sheet. This equation indicates thai the product of the area of the stripHK and h is equal to the moment of the strip CD. A similar resultmay be found Eor any other strip; hence, if a number of points,such as H and K, be found…
