Mechanics 2

Lectures

Goal

-to provide students knowledge of the fundamental principles of Kinematics and Particle Dynamics -to enable students to master the determination of motion, properties of motion of mechanical objects and determination the causes of motions -to prepare students for solving the problems in different engineering and scientific fields

Outcome

Upon successful completion of this course, students will be able to: • Analyze motion of a particle in various coordinate systems • Solve problems related to kinematics of a particle, i.e. to determine line of motion, trajectory, velocity, acceleration and sector velocity • Describe certain types of body motion: translation, rotation of a body about a fixed line, plane motion, spherical motion and general motion of a rigid body, as well as to determine kinematic quantities of a body (angular velocity and angular acceleration) and to determine velocity and acceleration of some points of a body • Solve kinematic problems related to the relative motion of a particle • Set differential equation related to the motion of a free and constrained particle, as well as to solve direct and inverse dynamic problem of a particle • Determine center of mass and inertia moments of a particle system and a rigid body
