What is the product moments of inertia of plane area about its own centroidal axis?
The product moments of inertia of a plane area about its own centroidal axes, often denoted as ( I_{xy} ), is a measure of how the area is distributed relative to its centroid. It is defined as ( I_{xy} = \int_A y , x , dA ), where ( A ) is the area, ( x ) is the distance from the centroid to a point in the area in the x-direction, and ( y ) is the distance in the y-direction. This value is crucial in structural engineering and mechanics for analyzing the behavior of beams and other structural elements under loading.

State ane prove perpendicular axis theorem?
In physics, the perpendicular axis theorem (or plane figure theorem) can be used to determine the moment of inertia of a rigid object that lies entirely within a plane, about an axis perpendicular to the plane, given the moments of inertia of the object about two perpendicular axes lying within the plane. The axes must all pass through a single point in the plane.Define perpendicular axes , , and (which meet at origin ) so that the body lies in the plane, and the axis is perpendicular to the plane of the body. Let Ix, Iy and Iz be moments of inertia about axis x, y, z respectively, the perpendicular axis theorem states that[1]This rule can be applied with the parallel axis theorem and the stretch rule to find moments of inertia for a variety of shapes.If a planar object (or prism, by the stretch rule) has rotational symmetry such that and are equal, then the perpendicular axes theorem provides the useful relationship:DerivationWorking in Cartesian co-ordinates, the moment of inertia of the planar body about the axis is given by[2]: On the plane, , so these two terms are the moments of inertia about the and axes respectively, giving the perpendicular axis theorem.

Why can't a car plane or bicycle stop immediately?
inertia
Why the cross product of two vectors in plane is directed perpendicular to the plane?
because that is the def. of a cross-product!
What is the moment of inertia of a circular disk rotating about an axis if the mass is m and radius is r?
The answer will depend on whether the axis isthrough the centre of the disk and perpendicular to its plane,a diameter of the disk, orsome other axis.Unless that information is provided, the answer is meaningless.
How does product travel?
By plane, boat or trucks....
How is angular momentum expressed in polar coordinates?
Angular momentum in polar coordinates is expressed as the product of the moment of inertia and the angular velocity, multiplied by the radial distance from the axis of rotation. This formula helps describe the rotational motion of an object in a two-dimensional plane.
How do you find out the moment of inertia of a plane area?
By integration. This means the plane is divided into small pieces, and the contribution of each individual piece to the moment of inertia is evaluated. There are mathematical methods to do this more or less easily - systematically, at least - for certain simple figures, and you can find the moment of inertial of many common figures published in lists.
What is inertia pair?
An inertia pair is a pair of elements in a molecule that are related by a symmetry operation, typically a twofold rotation axis or a mirror plane. These elements have identical chemical properties and are often used to simplify the analysis of molecular symmetry.
Consider a uniform square plate of side a and mass m the moment of inertia of this plate about an axis perpendicular to its plane and passing through one of its corners is?
The moment of inertia of a uniform square plate of side a and mass m about an axis perpendicular to its plane and passing through one of its corners is given by I = (1/3)ma^2.
