Just moment of inertia is incomplete requirement as the axis about which it is to be measured is also very important
moment of inertia is basically an objects resistance to its state of motion.
The centroid is the geometric centre of an object. Moment of inertia is a objects resistance to rotation and has the units kg.m^2
How do to determine the moment of inertia of a cub
Moment of Inertia of a disk (I) = 1/2MR2 Moment of Inertia of a disk (I) = 1/4MR2
Dimensional formula of moment of inertia = [ML2T0 ]
The second moment of a force is called as moment of inertia.
mass moment of inertia is the property of the body to resist rotation about the given axis where as the area moment of inertia is the resistance to bending about the given axis
Moment of inertia has unit kg m2
define moment of inertia§ I is the moment of inertia of the mass about the center of rotation. The moment of inertia is the measure of resistance to torque applied on a spinning object (i.e. the higher the moment of inertia, the slower it will spin after being applied a given force).
The moment of inertia tells us how easy or how difficult it is to make something rotate.
The moment of inertia formula isIxx= bh3 / 12B= base H= height and Ixx = moment of inertia of a rectagular section about x-x axis.
The moment of inertia of a hollow cylinder can be calculated with the help of the formula, I=0.5xMxRxR. Here I is inertia, M is mass and R is the radius.
