. .... n the figure below the two blocks are connected by a string of negligible mass passing over a frictionless pulley. m, = 10.0 kg and m, = 4.40 kg and the angle of the incline is 8 = 44.0°. Assume that he incline is smooth. (Assume the +x direction is down the incline of the plane.) (a) With what acceleration (in m/s) does the mas m, move on the incline surface? Indicate the direction with the sign of your answer. m/s? (b) What is the tension in the string in newtons? (c) For what value of m, (in kg) will the system be in equilibrium? kg
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).
