oblems will be given. Example I. — Find the center ofgravity of a triangle. Conceive the triangle, Fig. lo, tobe divided into a great number ofvery narrow strips drawn parallel toone of the sides, as B. The centerof gravity of each strip will be at itsmiddle point, therefore the center of gravity… … Fig. lo. b:B = h: H whence, b = f • Then Moment of elemental area Bh^dhH B r^ Moment of the whole ^ea = ^ / h^dh = BE- The area of the triangle EBE The distance, x^ of the center of gravity from the apex is BE - _ Moment of whole area _ 3 _ 2_EWhole area BE 3 That is, the center of gravity is at a…
