Details of Learning Activities

The learning activities in this course are designed to equip students with knowledge and skills in applying the principles of dynamics to specific items of machinery enabling the calculation of essenial parameters used for design.
The course will be using a combination of lectures, reading tasks, practical work and mainly tutorials/assignments to achieve these objectives.

Readings: Students may be required to read relevant section(s) of the recommended references/class notes prior to the next class.

Tutorial work & Practical Assignments challenge the students and ensure that participants apply and deepen the theoretical knowledge covered in lectures.
