  • Visualize the vibration of mechanical distributed systems in terms of waves.
 
 
2.4Teaching and Learning Activities
 
 Teaching methods include
 
2 lectures a week. Two laboratory classes. The typical lab class size is 20. Feedback is given by advice and assistance in the laboratory session.
Students join the course with widely varying background in dynamics and this is dealt with by proportionate assistance during the tutorial classes.
Students need to work in their own time to complete the homework exercises and are able to go to the lecturers for assistance. 
 
 Learning activities include
 
Home studying of the notes provided during lectures. Also students are encouraged to study on their own the material presented in class by consulting the reference books suggested for the course. Finally students are requested to work on a set of exercises that are based on the teaching and class tutorial examples.

2.6Feedback to students during module study (formative assessment)
 
  • Tutorial assistance to cover issues raised through example sheets.
  • Tutorial exercise classes provide informal assessment through individual interaction.
Interactive web notice-board that enables students to write and share comments and observations about the subject.
 
2.7Relationship between the teaching, learning and assessment methods
 
The course is divided into three parts: first, fundamental of dynamics; second, SDOF vibration theory and third, wave propagation in beams. The three parts are organised in such a way as to guide the students from their common background knowledge of physics (kinematics and kinetics of particles) to more advanced theory of mechanical systems (kinematics of rigid body systems) and to the introductory concepts of free and forced vibrations of SDOF systems and fundamentals of wave propagation in beams. This incremental process is assessed through the exam papers. Students are requested to answer one out of two questions for the three subjects of the course ( dynamics, SDOF vibration and waves). In this way the level of progression from the entry point of the Acoustical Engineering and Acoustic with/and Music programmes is assessed.
