consider a particle of certain mass is attached to one end of a string of fixed length equal to 23.1cm. The other end of the string is fixed to the ground. Initially, the particle is sitting in the ground at rest. Suppose a tangential velocity of 23.4m/s is given to the particle for 12.9s, find the andular acceleration of the string
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).
