Inertia of a rod rotating about the center
WebA. When rotating about the end of the rod, it will be unbalanced and question: The moment of inertia of a uniform rod about an axis through its center is 1/12mL^2. The moment of inertia about an axis at one end is 1/3mL^2. Why is the moment of inertia is larger when rotating about the end of the rod than when rotating about the center of the rod? WebThe four particles in the figure below are connected by rigid rods. The origin is at the center of the rectangle. If the system rotates in the x-y plane about the z-axis with an angular speed of 6 rad/s, calculate (a) the moment of inertia of the system about the z-axis and (b) the rotational energy of the system. Solution: Concepts:
