Regardless of the mode of delivery, represent a guide to the relative teaching time and student effort required to successfully achieve a particular competency/module. This may include not only scheduled classes or workplace visits but also the amount of effort required to undertake, evaluate and complete all assessment requirements, including any non-classroom activities.

Pre-requisites and Co-requisites

The following modules (or equivalents) should be preferably completed prior to, or in conjunction with, this module:
&#61656; EA 772 Introductory Dynamics

Course Description

To enable students to solve engineering problems involving Friction, Centrifugal Force, Balancing, Mechanical, Vibrations, Impulse, Momentum, Impact and Systems of Bodies in Motion.

National Codes, Titles, Elements and Performance Criteria

 National Element Code & Title: EB771 Advanced Dynamics

Learning Outcomes

1. Solve simple problems involving friction with respect to band brakes, clutches, belt drives, disc brakes, plain journal and plain thrust bearings, rolling resistance and power screws.
2. Calculate the centrifugal forces caused by bodies moving in circular paths.
3. Carry out a static and dynamic balance of unbalanced masses onshafts and flywheels and determine dynamic bearing reactions.
4. Define the conditions under which simple harmonic motion and resonance occur and solve simple problems of vibration isolation and transmissibility.
5. Solve problems on direct central impact for bodies whose coefficient of restitution is in the range 0 to 1.
6. Solve more advanced problems of accelerating bodies connected so that their motions are dependent upon one another using the work energy method.

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.
