The polar moment of resistance, often denoted as ( J ), is a measure of an object's ability to resist torsional (twisting) deformation. It is calculated as the integral of the squared distance from the axis of rotation over the entire cross-sectional area of the object. A larger polar moment of resistance indicates a greater capacity to withstand torsional loads without deforming. It is particularly relevant in the design of shafts and other structural elements subjected to twisting forces.

Is ki polar or non polar?
yes. it has a dipole moment.
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.
Is IO2 polar?
Yes, IO2 is polar. The molecule has an uneven distribution of electrons which gives rise to a permanent dipole moment, making it polar.
What is dipole moment of solvents?
The dipole moment of a solvent is a measure of its polarity, which indicates the separation of positive and negative charges within the molecule. Highly polar solvents have a large dipole moment, while nonpolar solvents have a dipole moment close to zero. The dipole moment of a solvent influences its ability to dissolve polar or ionic solutes.
Why phenol has lesser dipole moment than alcohol?
As we know that dipole moment of polar molecules is greater than non-polar. In other words, in molecules where charge separation is more, it is more polar and hence having more dipole moment. In phenol, due to resonance, there is positive charge on oxygen. So there is no more charge difference between carbon of ring and oxygen of OH group. This is the reason, it has less dipole moment.
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 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 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.
S2F2 is polar or non polar?
Think of the sulfite ion as a molecule with its geometry and dipole moment AND a net charge. The electron pair geometry is tetrahedral and the molecular geometry is trigonal pyramidal and because of its asymmetrical shape and polar bonds, sulfite has a net dipole moment (2.04D ). The ion is polar.
What is the unit for a polar moment of inertia?
Moment of inertia has unit kg m2
Is NH3 has zero dipole moment?
NH3 is polar compound.So dipole moment is not zero.
Does a polar molecule have a net dipole moment?
Yes, a polar molecule has a net dipole moment because it has a separation of charges, creating a partial positive and a partial negative end within the molecule. This results in an overall dipole moment, making the molecule polar.
