Allow M to be mass of a rod and let L be the length. Solve the given problem. Given: Part A) Let's say a rod of mass and length spun around a pOint L/3 from one end, look for the determination of the moment of inertia. Part B) A distance of L/6 from the pivot point was given to the center of this shape, find the angular velocity if the rod is allowed to rotate because of the gravitation thats from a horizontal position to a vertical position.
Rigid Body
A rigid body is an object which does not change its shape or undergo any significant deformation due to an external force or movement. Mathematically speaking, the distance between any two points inside the body doesn't change in any situation.
Rigid Body Dynamics
Rigid bodies are defined as inelastic shapes with negligible deformation, giving them an unchanging center of mass. It is also generally assumed that the mass of a rigid body is uniformly distributed. This property of rigid bodies comes in handy when we deal with concepts like momentum, angular momentum, force and torque. The study of these properties – viz., force, torque, momentum, and angular momentum – of a rigid body, is collectively known as rigid body dynamics (RBD).
