GRAVITATION 9 figure and the distance of its center of gravity from thechosen axis, then we add these products together anddivide their sum by the sum of the areas of the simplefigures. For example, in the figure shown, the area of rectanglenumber 1 is 2 X 13^^ or 3 sq. in. The area of No. 2 is6 X… … Fig. 8. sum of the products of these areas by the distances oftheir respective centers of gravity from axis ah gives3 XI + 18 X 3 + 4 X 5 or 77. Dividing this by thesum of the areas of the simple figures we have 77 77 ^^* 3+T8+4 ^^ 25 ^^ ^-0^ ^^- which is the distance of the center of gravity of…
