Objectives
Characterization of the motions of solids. Velocity and acceleration fields for relative and absolute motions of mechanisms. Preparation for the subsequent determination of dynamic forces.
Introduce and develop the fundamental concepts of rigid body dynamics: Force, mass and acceleration, work and energy and impulse and momentum.
Dynamic analysis of plane and three dimensions mechanisms.
Program
Mechanics II (Mecânica II) Kinematics of mechanisms. Kinematics of particles. Kinematics of solids. Theory of relative motions. Motions of solids permanently in contact.
KINECTICS OF RIGID BODIES:
Linear and angular momentum of a rigid body. Rate of change of the linear and angular momentum. Kinetic energy of a rigid body.
RIGID BODY DYNAMICS:
Force, mass and acceleration: Equations of motion of rigid bodies and mechanisms, in plane motion and in three dimensions. D’Alembert’s principle.
Work and Energy: Work of the forces acting on a rigid body. Power. Work of conservative and non-conservative forces. Work and kinetic energy, principle of energy conservation. Virtual displacement, virtual work and principle of virtual work.
Impulse and momentum: Linear and angular impulse. Principle of impulse and momentum for a rigid body. Conservation of momentum. Impact. Central and eccentric impact.
