ivenia the Cartesian coordinates the mass of an infinitesimalcube is taken as the ele-ment of mass: dm = T dxdy dz. (b) When the boundingsurfaces of the body aregiven in spherical coordi-nates the element of massis chosen as shown in Fig.80. In this case the fol-lowing is the expression forthe… … Fig. 80. 148 ANALYTICAL MECHANICS ILLUSTRATIVE EXAMPLES. 1. Find the center of mass of an octant of a homogeneous sphere,(a) Suppose the bounding surfaces to be x^ + y^ + z^ = a^, X = 0, y = 0, and 2 = 0.Then the Umits of integration are X = 0 and x = a, y = 0 and y = Va^ — x^, g = 0 and z = ^/a —…
