The moment of inertia of thin uniform rectangular plate relative to the axis passing perpendicular to the plane of the plate through one of its vertices if the sides of the plate are equal to a and b and mass m is I m x a 2 b 2.

Consider it to have n parallel slices n being very large number along x direction so that each slice a like a rod of mass mn and length a. The Moment of Inertia for a Thin Rectangular Plate calculator compute the moment of inertia based on the mass and two dimensions of the plate height and width. Moments of Inertia for a rectangular plane with axis along edge.

Here b is used to denote the rectangle width the dimension parallel to the axis and h is said to be the height dimension perpendicular to the axis. Rectangular Plate Mass Moment of Inertia Calculator About Edge Design Variables Length L in mm m lbs g Results I lbm-in 2 g-mm 2. You need to know the moment of inertia around an axis that is parallel and passes through the center of mass.

I m L 2 12. M ρ x bdt. I Icm mh².

Calculate the moment of inertia for a thin rectangular plate with the axis of rotation along the long edge. Now to find the moment of inertia use the standard method of integrating over r2dm. Moment of inertia of the thin uniform rod through center with a length 3 m and mass 4 kg.

For an axis along its shorter edge. When we take a situation when the axis passes through the centroid the moment of inertia of a rectangle is given as. Moments of Inertia for a slender rod with axis through center.

Find Moment of Inertia of a Square Plate along an Axis. For an axis of rotation perpendicular to the plate through its center b. I frac b h3 12 where b is the rectangle width and specifically its dimension parallel to the axis and h is the height more specifically the dimension perpendicular to the axis.

The parallel axis theorem is a useful relationship to find the moment of inertia of an object around any axis. Then the distance from xy to the axis of rotation passing through 00perpendicular to the plate is x 2 y 2 and the moment of inertia is itexint_-a2a2int_-b2b2rho x2 y2dydx itex. I ρ b dy ty 2.
