Moment of Inertia Formula, Definition, Equations, Units, Examples
The moment of inertia, or more accurately, the second moment of area, is defined as the integral over the area of a 2D shape, of the squared distance from an axis: where A is the area of the shape and y the distance of any point inside area A from a given axis of rotation.
Moment of Inertia of Rectangle
The moment of inertia is related to the rotation of the mass; specifically, it measures the tendency of the mass to resist a change in rotational motion about an axis. The moment of inertia \(I_x\) about the \(x\)-axis for the region \(R\) is the limit of the sum of moments of inertia of the regions \(R_{ij}\) about the \(x\)-axis. Hence
Moment of Inertia of Rectangular Section YouTube
The moment of inertia of an object around an axis is equal to I = ∬ R ρ2dA where ρ is the distance from any given point to the axis. In the case of a rectangular section around its horizontal axis, this can be transformed into

How to find Moment of Inertia of rectangular section YouTube
The moment of inertia of an area about an axis is a concept appearing in the formulations of several physical phenomena. The moment of inertia of an area is a geometric property of the area. Its value reflects how strong an object (i.e. stiffness) is against bending or twisting about some axis.
Solved Determine the moments of inertia of the rectangular
Moment of Inertia (Iz, Iy) - also known as second moment of area, is a calculation used to determine the strength of a member and it's resistance against deflection. The higher this number, the stronger the section. There are two axis here:
Second Moment of Area of a Rectangle (Parallel Axis Theorem) YouTube
In summary, the formula for determining the moment of inertia of a rectangle is Ixx=BD³ ⁄ 12, Iyy=B³D ⁄ 12. For rectangular hollow sections, the formula is Ixx=BD³ ⁄ 12 - bd³ ⁄ 12. The moment inertia is important for both bending moment force/stress and deflection.
