Why moment of inertia is also called rotational inertia?
Because it is a measure of the "resistence" of an object to be accelerated in its rotation. An object with a big moment of inertia is more difficult to increase/decrease its angular velocity (speed of rotation), than an object with a low moment of inertia.
Unit for a measure of resistance to a change of motion?
The inertia. This is directly related to the object's mass.
Why dipole moment is zero in non polar molecules non zero in polar molecules?
The dipole moment is zero in nonpolar molecules and non-zero in polar molecules due to electronegativity. Polar molecules have balanced electronegativity that will cancel one another out, while nonpolar molecules have unbalanced electronegativity causing dipole moments.
Inertia can be categorized as?
Resting Inertia and Moving Inertia
What is the component of inertia?
Inertia depends on mass.
What is difference between polar moment of inertia and moment of inertia?
Polar moment of inertia of an area is a quantity used to predict an object's ability to resist torsion.Moment of inertia, also called mass moment of inertia or the angular mass, (SI units kg m2, Imperial Unit slug ft2) is a measure of an object's resistance to changes in its rotation rate.
What is the SI unit of inertia?
The unit of Inertia is kg and the Moment of Inertia is kg*m^2
To design a building which type of moment of inertia you use about xaxis about yaxis or polar moment of inertia?
We use y_y axes
What is polar moment of inertia of motor load system?
It is impossible to tell you exactly what the polar moment of inertia is for a motor load system just from your question. We would need to know the specifications of the motor load system to make that calculation.
Can you find torque by time in moment of inertia?
Comparing linear and circular motion we can see that moment of inertia represents mass and torque represents force. So the product change in the circular momentum per unit time is torque. Circular momentum is the product of moment of inertia and circular velocity.
How do you determine the moment of inertia?
How do to determine the moment of inertia of a cub
How do you find Polar moment of inertia of a 3d rigid body?
As with many other physical quantities, you need to use integration.
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
What is rotational inertia?
Rotational inertia is sometimes called spin. It involves the movement of a mass around an axis. This moving mass will have some measure of kinetic energy that is due to the fact that it is spinning. The variables are the shape and the mass of the object, the way the mass is distributed within the object, the speed of its rotation, and the location of the axis of spin through the object. The moment of inertia might also be called angular mass, mass moment of inertia, rotational inertia, or polar moment of inertia of mass. Use the link below for more information.
