listen to the pronunciation of polar atalet momenti
التركية - الإنجليزية
polar moment of inertia
A measure of a body's resistance to twisting; a measure of torsional strength
same principle as Moment of Inertia only x2, y2 and xy are replaced with r2 (i e uses radius in it's calculation)
Is the sum of any two moments of inertia about axes at right angles to each other It is taken about an axis which is perpendicular to the plane of the other two axes
The resistance of an object to rotational acceleration When the mass of an object is distributed far from its axis of rotation, the object is said to have a high polar moment of inertia When the mass distribution is close to the axis of rotation, it has a low polar moment of inertia A mid-engined car has most of its mass within its wheelbase, contributing to a low polar moment of inertia, which, in turn, improves cornering turn-in
The moment of inertia of a body about an axis perpendicular to plane of its surface is called polar moment of inertia Hence, polar moment of inertia is a mass distribution property about an axis perpendicular to its surface
