Derivation of the moment of inertia of a uniform rod of mass m and length l, wrt axis passing through the center of the rod and perpendicular to the length of the rod. 06:59 - 14:05 RBD Problem 1: Based on the rod's MoI (Moment of Inertia). In this problem, we have a uniform rod of mass m and length l, and we have to find the moment of inertia of the rod wrt the axis passing through a point at l/4 distance from the one end of the rod and perpendicular to the rod. ABJ Sir derived the formulae of the given condition with two methods. 14:09 - 22:23 Moment of Inertia (MoI) of Uniform Rectangular plate: Derivation of the moment of inertia of a uniform rectangular plate of mass m, length l, and width b wrt. Axis passing through one end of the plate (as given diagram). 22:23 - 26:47 Moment of Inertia (MoI) of Ring: Derivation of the moment of inertia of a ring of mass m and radius R wrt axis passing through the center of the ring and perpendicular to the plane of the ring. 26:57 - 30:27 Moment of Inertia (MoI) of a semicircular ring/Circular arc: Derivation of the moment of inertia of a semicircular ring of mass m and radius R wrt axis passing through the center of the ring and perpendicular to the plane of the ring. 30:27 - 35:18 Moment of Inertia (MoI) of a Hollow Cylinder: Derivation of the moment of inertia of a Hollow Cylinder of mass m and radius R wrt axis passing through the center of the hollow cylinder. 35:18 - 41:18 Moment of Inertia (MoI) of Disc: Derivation of the moment of inertia of a Disc of mass m and radius R wrt axis passing through the center of the ring and perpendicular to the plane of the ring. 41:20 - 43:23 RBD Problem 2: Based on the Moment of Inertia of a Disc. In this problem, we have a semi-circular disc of mass m and radius R, and we have to find the moment of inertia of the given disc wrt axis passing through the center of the disc and perpendicular to the plane of disc. 43:23 - 45:18 RBD Problem 2: Based on the Moment of Inertia of a Disc. In this problem, we have a quarter disc of mass m and radius R, and we have to find the moment of inertia of the given disc wrt axis passing through the center of the disc and perpendicular to the plane of disc. 45:18 - 49:22 Moment of Inertia (MoI) of a Solid Cylinder: Derivation of the moment of inertia of a Solid Cylinder of mass m and radius R wrt axis passing through the center of the Solid Cylinder. 49:22 - 59:23 Moment of Inertia (MoI) of a Hollow Sphere: Derivation of the moment of inertia of a Hollow Sphere (Spherical Shell) of mass m and radius R wrt axis passing through the center of the Hollow Sphere. 59:23 - 01:09:32 Moment of Inertia (MoI) of a Solid Sphere: Derivation of the moment of inertia of a Solid Sphere of mass m and radius R wrt axis passing through the center of the Solid Sphere. 01:09:32 - 01:16:03 RBD Problem 3: Based on the moment of inertia of a non uniform solid sphere. In this problem we have a non uniform solid sphere of radius R and the density function of the solid sphere and we have to find the moment of the solid sphere wrt axis passing through the center of the body. 01:16:03 - 01:28:59 Moment of Inertia (MoI) of a Solid Cone: Derivation of the moment of inertia of a Solid cone of mass m and Base radius R wrt axis passing through the center of the Solid Cone.
