An electric celing fan is rotating about a fixed axis with an initial angular velocity magnitude of 0.290 rev/s. The magnitude of the angular acceleration is 0.008 rev/s Both the the angular velocity and angular accleration are directed clockwise. The electric celing fan blades form a circle of diameter 0.700 m. Part D What is the magnitude a of the acceleration of a point on the tip of the blade at time t0205? • View Avallable int(s) m/s
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).
