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 the equation for calculating the polar moment of inertia of a cylinder?
The equation for calculating the polar moment of inertia of a cylinder is I ( r4) / 2, where I is the polar moment of inertia and r is the radius of the cylinder.
What is the formula for calculating the polar moment of inertia for a cylinder?
The formula for calculating the polar moment of inertia for a cylinder is I (/2) r4, where I is the polar moment of inertia and r is the radius of the cylinder.
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 formula for calculating the polar moment of inertia of a cylinder and how does it differ from the moment of inertia about the centroidal axis?
The formula for calculating the polar moment of inertia of a cylinder is Ip 0.5 m r2, where m is the mass of the cylinder and r is the radius. The polar moment of inertia measures an object's resistance to torsional deformation, while the moment of inertia about the centroidal axis measures an object's resistance to bending.
What is the formula for calculating the polar moment of inertia of a cylinder?
The formula for calculating the polar moment of inertia of a cylinder is I (/2) r4, where r is the radius of the cylinder.
What is the formula for calculating the polar moment of inertia of a hollow cylinder?
The formula for calculating the polar moment of inertia of a hollow cylinder is J /2 (router4 - rinner4), where J is the polar moment of inertia, router is the outer radius of the cylinder, and rinner is the inner radius of the cylinder.
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 the SI unit of inertia?
The unit of Inertia is kg and the Moment of Inertia is kg*m^2
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 find Polar moment of inertia of a 3d rigid body?
The polar moment of inertia of a 3D rigid body can be found by integrating the square of the distance from the axis of rotation for all the infinitesimally small elements of mass in the body. This integral takes into account both the area moment of inertia and the mass distribution of the body. The final result is a measure of the body's resistance to torsional deformation.
What is the domensions for moment of inertia?
Dimensional formula of moment of inertia = [ML2T0 ]
