PROBLEM 9.63 Determine the x coordinate of the centroid of the volume shown. ( Hint: The height y of the volume is proportional to the x coordinate; consider an analogy between this height and the water pressure on a submerged surface.) SOLUTION Have EL x dV x dV = where and EL dV ydA x x = = Now 60 1 300 5 yx x == Then 1 5 1 5 x xd A x x dA    = ( ) () 2 z A A I xdA xdA xA where ( ) z A I is the moment of inertia of the area with respect to the
