 Abstract Kinematics, dynamics and oscillations: Motion of a single particle - Motion of systems of particles - 2D and 3D motion of rigid bodies Vibrations Objective This course provides Bachelor students of mechanical engineering with fundamental knowledge of kinematics and dynamics of mechanical systems. By studying motion of a single particle, systems of particles and rigid bodies, we introduce essential concepts such as work and energy, equations of motion, and forces and torques. Further topics include stability of equilibria and vibrations. Examples presented in the lectures and weekly exercise lessons help students learn basic techniques that are necessary for advanced courses and work on engineering applications. Content 1. Motion of a single particle || Kinematics: trajectory, velocity, acceleration, inertial frame, moving frames - Forces and torques. Active- and reaction forces. - Linear momentum principle, angular momentum principle, work-energy principle - Equations of motion; 2. Motion of systems of particles || Internal and external forces - Linear momentum principle, angular momentum principle, work-energy principle - Rigid body systems of particles; conservative systems 3. 3D motion of rigid bodies || Kinematics: angular velocity, velocity transport formula, instantaneous center of rotation - Linear momentum principle, angular momentum principle, work-energy principle - Parallel axis theorem. Angular momentum transport formula 4. Vibrations || 1-DOF oscillations: natural frequencies, free-, damped-, and forced response - Multi-DOF oscillations: natural frequencies, normal modes, free-, damped-, and forced response - Estimating natural frequencies and mode shapes - Examples Lecture notes Hand-written slides will be downloadable after each lecture. Literature Typed course notes from the previous year Prerequisites / Notice Please log in to moodle ( https://moodle-app2.let.ethz.ch/auth/shibboleth/login.php ), search for "Dynamics", and join the course there. All exercises sheets, lecture materials etc. will be uploaded there.

### Performance assessment

 Performance assessment information (valid until the course unit is held again) Performance assessment as a semester course In examination block for Bachelor's Programme in Civil Engineering 2014; Version 01.08.2016 (Examination Block 1)Bachelor's Programme in Mechanical Engineering 2010; Version 03.10.2017 (Examination Block 1) ECTS credits 6 credits Examiners P. Tiso, G. Haller Type session examination Language of examination English Repetition The performance assessment is offered every session. Repetition possible without re-enrolling for the course unit. Mode of examination written 150 minutes Additional information on mode of examination Written multiple choice exams (2 midterm exams: (Dates will be announced during the course), one final exam). Midterm exams are optional and will count up to 30% of the final grade if they improve the grade of final exam. Written aids All students are provided with a list of formulas (without explanation). No calculators or other resources are allowed. If the course unit is part of an examination block, the credits are allocated for the successful completion of the whole block.This information can be updated until the beginning of the semester; information on the examination timetable is binding.
