The following notation is used in the problems: M = mass , x ¯ , y ¯ , z ¯ = coordinates of center of mass (or centroid if the density is constant), I = moment of inertia (about axis stated), I x , I y , I z = moments of inertia about x, y, z axes, I m = moment of inertia (about axis stated) through the center of mass. Note: It is customary to give answers for I , I m , I x , etc., as multiples of M (for example, I = 1 3 M l 2 ). A uniform chain hangs in the shape of the catenary y = cosh x between x = -1 and x = 1 . Find (a) its length, (b) y ¯ .
