There are 2 thin uniform rods. Rod DC is pinned at its center of gravity (free to rotate 360 degrees), 6 FT long, and perfectly horizontal. Rod AB is perfectly vertical, pinned at the bottom of the rod and 6 FT long as well. Both pins are on the ground (So they form a perfectly horizontal line if you connect them). The pines are 9 FT away from each other. Rod AB is released from rest and hits the end of DC with a coefficient of restitution of 0.6 . DETERMINE THE ANGULAR VELOCITY OF BOTH RODS JUST AFTER IMPACT ASSUMING BOTH WEIGH 20 LBS EACH.
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).
