According to Newton’s Laws, objects will stay in their current state of motion unless something acts upon them. While Newton’s Laws are usually applied to linear motion, they also apply to rotation. A rotating object will continue to rotate unless a force acts on it. How quickly an object rotates depends on its mass properties […]

Why Is Moment of Inertia Important? The moment of inertia (MOI) is one of the many mass properties that describe an object’s stability and the forces needed to alter its motion. For aerospace engineering, stability is a crucial element in designing and manufacturing air and spacecraft. Knowing the MOI about various axes is vital to determining how a device […]
