Moment of inertia shape
Web9 sep. 2024 · Moment of inertia or mass moment of inertia is the resistance of a rigid body to change in its angular velocity or we can say, resistance to angular acceleration, when a net external torque acts on it (similar to resistance offered by mass of a particle to acceleration, when a net force acts on it). WebUnlike the rectangular moments of inertia, which are always positive, the product of inertia may be either positive, negative, or zero, depending on the object's shape and the orientation of the coordinate axes. The product of inertia will be zero for symmetrical objects when a coordinate axis is also an axis of symmetry. 🔗
