Because you need to overcome inertia before you can lift anything

How do you decide the object which has the highest moment of inertia out of two objects?
Just moment of inertia is incomplete requirement as the axis about which it is to be measured is also very important
How do you determine the moment of inertia?
How do to determine the moment of inertia of a cub
Mass moment of inertia of a disk?
Moment of Inertia of a disk (I) = 1/2MR2 Moment of Inertia of a disk (I) = 1/4MR2
What is the domensions for moment of inertia?
Dimensional formula of moment of inertia = [ML2T0 ]
What is meant by moment of inertia in Induction motors?
The second moment of a force is called as moment of inertia.
What is the difference between mass moment of inertia and area 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 and torsional vibrations?
in torsional vibrations moment of inertia is a very important determining factor. it is a quantitative measure of the resistance of an object to torsion. it is synonymous to mass in displacement systems. the greater the moment of inertia the lesser the degree of torsional vibrations and vice versa. moment of inertia relates torsional vibrations to the geometry of the part considered irrespective of its composing material and its strength.
What is the unit for a polar moment of inertia?
Moment of inertia has unit kg m2
Mass moment of inertia of a flywheel?
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).
What variables contribute to moment of inertia?
The axis about which the body is being rotated and the geometry of the body are important. The further away material (in terms of area) is from the centroid of the body the higher the moment of inertia will be, which is why an I-beam is good in bending. If it's the mass moment of inertia which is used in dynamics for Euler's angular momentum equation. Then the mass of the body is important. The further away mass is from the axis of rotation the greater the mass moment of inertia will be. This is why when a figure skater pulls their arms into her body during a spin she begins to spin faster. The mass of their arms is now closer to their axis of rotation lowering their mass moment of inertia and decreasing their resistance to rotation.
Must an object be rotating to have a nonzero moment of inertia?
moment of inertia is basically an objects resistance to its state of motion.
Importance of moment of inertia?
The moment of inertia tells us how easy or how difficult it is to make something rotate.
