Center of mass of a hollow cylinder
The following is a list of centroids of various two-dimensional and three-dimensional objects. The centroid of an object in -dimensional space is the intersection of all hyperplanes that divide into two parts of equal moment about the hyperplane. Informally, it is the "average" of all points of . For an object of uniform composition, the centroid of a body is also its center of mass. In the case of two-dimensional objects shown below, the hyperplanes are simply lines. WebThe sphere weighs 30lbs, the slender rod weighs 10lbs, and the hollow cylinder has a density of 50lb/ft3. Ans: Iyy=27.0 slug- ft2; Question: Find the mass moment of Inertia Iyy for the composite body shown below. The sphere weighs 30lbs, the slender rod weighs 10lbs, and the hollow cylinder has a density of 50lb/ft3. Ans: Iyy=27.0 slug- ft2
