Define moments of inertia
WebThe area moment of inertia is a property of a two-dimensional plane shape which characterizes its deflection under loading. It is also known as the second moment of area or second moment of inertia. The area moment of inertia has dimensions of length to the fourth power. Unfortunately, in engineering contexts, the area moment of inertia is often … WebIf the body is divided into infinitely small pieces with mass dm, then the moment of inertia will be equal to the sum of the product of these elementary masses by the square of the distance to the axis of rotation. The formula will look like this: J is the moment of inertia, r is the distance to the axis of rotation.
