There are several ways to define spherical measure. One way is to use the usual "round" or "arclength" metric ρn on S ; that is, for points x and y in S , ρn(x, y) is defined to be the (Euclidean) angle that they subtend at the centre of the sphere (the origin of R ). Now construct n-dimensional Hausdorff measure H on the metric space (S , ρn) and define One could also have given S the metric that it inherits as a subspace of the Euclidean space R ; t… Web4 Bolt Square Flange Block; 3-7/16" Bore; 9.9" Bolt Circle; 7" Bolt Spacing; 1 Piece Solid; Concentric Collar Mount; Cast Steel; Spherical Roller Bearing; 4.03" Length Thru Bore; Relubricatable; Teflon Labyrinth Seals
