Moment of Inertia - Derivation for a Solid Sphere - OnlyPhysics

WebIt turns out that the friction force needed to stop a ball on a ramp from sliding is a function of the moment of inertia. You can see a detailed derivation of (most of) this in this earlier answer I wrote. The implication is that the solid ball will roll without slipping on a steeper slope than the corresponding hollow ball - the critical angle ... Web2 Density of disc = (kg/m2) Radius of disc = R (m) Therefore, mass of disc = M = area × density = R2 (kg) Split the disc into elementary rings of radius r and width dr: Mass of ring = area × density = 2 r dr As all the mass is at the same radius, moment of inertia of ring = 2 r dr r2 = 2 r3 dr Therefore, moment of inertia of disc = ∫2 πρ ݎଷ ݀ݎ WebImportantly, (7) is based on the moment of inertia equaling mr 2, which describes a point mass, a ring, or a hollow cylinder with open ends . This moment does not equal that of any closed 3D shell, including spherical shells and homeoids [ 40 ], … command to install microsoft 365 apps in odt
