MECH20442 Dynamics 10 Semester 2 Undergraduate Level 2 Akin Atas Unit coordinator 1 FHEQ level (Framework for Higher Education Qualifications) ' Middle part of Bachelors ' European Credit Transfer & Accumulation System Rating : 5.0 Dynamics will continue to broaden the students’ knowledge of mechanical systems by extending rigid body kinematics and kinetics into three dimensions using real world examples and applications.  The unit will also introduce students to approaches used to analyse the dynamic response of structures.  The unit is run over twelve weeks with 2 hours of lectures per week and 1 hour of tutorial every alternate week.  Assessment will be via an unseen examination (80%) and coursework (20%).  Dynamics will continue to broaden the students’ knowledge of mechanical systems by extending rigid body kinematics and kinetics into three dimensions using real world examples and applications.  The unit will also introduce students to approaches used to analyse the dynamic response of structures.  The unit is run over twelve weeks with 2 hours of lectures per week and 1 hour of tutorial every alternate week.  Assessment will be via an unseen examination (80%) and coursework (20%). The aim of the unit is to further develop the students’ understanding and skills in the analysis of mechanical systems that are in motion. Vibrations The students will be shown how structures and systems respond when they undergo free and forced vibration (in both undamped and damped systems) and how this behaviour can be analysed.  By the end of the topic, the students will be able to:1. simplify problems to one degree-of-freedom mass-spring-damper systems, 2. determine the characteristics of those systems, 3. analyse the response of the systems using the equation of motion method, and 4. extend the methodology to undamped two degree-of-freedom systems. Three-dimensional kinematics of a rigid body The students’ knowledge of rigid body kinematics will be extended from two-dimensions into three-dimensions and they will be given the techniques with which they can analyse the velocities of such systems.  By the end of the topic, the students will be able to:1. identify the motion of the system under investigation, 2. choose the appropriate analysis methodology, 3. analyse the kinematics of rigid bodies subjected to rotation about a fixed point and general motion, and 4. conduct relative-motion analyses of rigid bodies using translating and rotating axes. Three-dimensional kinetics of a rigid body The students’ knowledge of rigid body kinetics will be extended from two-dimensions into three-dimensions and they will be given the techniques with which they can analyse the forces within such systems.  By the end of the topic, the students will be able to:1. find the moments and products of inertia of a rigid body about various axes, 2. apply the principles of work and energy, and linear and angular momentum to rigid bodies having three-dimensional motion, 3. develop and apply the equations of motion in three dimensions, and 4. analyse gyroscopic motion. 0 Other 20% 1 Written exam 80% Other:Two Blackboard-based quizzes that test the student's understanding of the topics taught during that period  Exam - via script viewingQuizzes - marks and solutions released one week after submission BEng(Hons) Aerospace Engineeri BEng(Hons) Aerospace Engineeri Second Year Mandatory BEng(Hons) Mechanical Engineer BEng(Hons) Mechanical Engineer Second Year Mandatory BEng(Hons) Mechanical Engineer BEng(Hons) Mechanical Engineer Second Year Mandatory MEng (Hons) Aerospace Engineer MEng (Hons) Aerospace Engineer Second Year Mandatory MEng (Hons) Aerospace Engineer MEng (Hons) Aerospace Engineer Second Year Mandatory MEng (Hons) Aerospace Engineer MEng (Hons) Aerospace Engineer Second Year Mandatory MEng (Hons) Mechanical Enginee MEng (Hons) Mechanical Enginee Second Year Mandatory MEng (Hons) Mechanical Enginee MEng (Hons) Mechanical Enginee Second Year Mandatory MEng (Hons) Mechanical Enginee MEng (Hons) Mechanical Enginee Second Year Mandatory BEng (Hons) Mech Eng (Nuc Eng) BEng (Hons) Mech Eng (Nuc Eng) Second Year Mandatory MEng (Hons) Mech Eng (Nuc Eng) MEng (Hons) Mech Eng (Nuc Eng) Second Year Mandatory N Lectures 24 Tutorials 6 0 70
