Basics of Mechanics 2

Lectures

Goal

-to provide students knowledge of the fundamental principles of particle kinematics and particle dynamics -to enable students to master the determination of motion of a particle, dynamics of a free and constrained particle, linear straight line vibrations of a particle, basic theorems and laws of a particle - 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 • 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 • Solve problems of linear straight line vibrations of a particle •Form expressions for momentum and angular momentum of a particle • Determine kinetic energy of a particle •Apply impulse-linear momentum theorem, angular impulse-angular momentum theorem and work-kinetic energy theorem of a particle • Solve motion problems of a particle under central force
