Two mass are conected to cach with a rope which passes over a frictionless pulley having a radius of 30.0 cm and an unknown moment of inertia. Mass 1 hangs over the edge of the table and mass 2 slides on top of the table. The coefficient of friction between the top of the table and mass 2 is 0.250. When the system is released from rest the system accelerates at 3.00 m/s². Mass 1 = 60 kg and Mass 2 = 40 kg. What is the tension in the string which is connected to mass 1? 328 N O 528 N 120 N O 98.0 N O 180 N 980 N 408 N O 588 N
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).
