gravityof a polygon can be found by dividing it into triangles,taking the centre of gravity of each by the above articleand then proceeding as in Art. 161. The weights ofthe triangles are taken as proportional to their areas. 167. The Centre of Gravity of a Solid Figure. Thecentre of gravity of a… … 178 STATICS. [168, ty will lie in their line of intersection; and if three, atthe point in which they all intersect. Therefore thecentre of gravity of a sphere is at its centre; of a cylin-der, at the middle point of its axis; of a rectangularsolid, at the point of intersection of three planes…
