Problem 1: The system shown is consists of a cylinder 0.80m in diameter weighing 250N that rests on the horizontal floor and attached to it and concentric with it is a hollow cylinder 0.40m in diameter around which a cord is wrapped. Solve for the force P to produce an a=4m/s. Find the frictional force F and the linear velocity of the center after moving 12m from rest. Use I= mr?. P. 0.2m 0.4m IN
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).
