Rationale and Purpose of the Module:

The objective of this module is to develop an ability to apply the principles of engineering mechanics in solving common problems involving mechanisms such as linkages, cam/followers and gear trains.

Syllabus:

1. Kinematics of Simple Mechanisms and Linkages: * Four-bar linkages and straight line mechanisms. * Position, velocity and acceleration analysis of linkages. * Problem solving using velocity and acceleration vector diagrams. * Analysis of linkages influenced by Coriolis effects. 2. Cam/Follower Systems: * Kinematic analysis of follower motion; velocity and acceleration. * Graphical cam design. 3. Gear Trains: * Gear kinematics and dynamics * Simple and compound trains. * Epicyclic gear trains * Torque and power transmission. 4. Balancing: * Balancing of rotors; static and dynamic balancing. * Balancing of reciprocating masses. 5. Oscillatory Motion: * Free and forced vibration of particles. * Rigid body vibration. * Vibration analysis of mechanisms. 6. Gyroscopic Motion: * Steady-state gyroscopic precession. * Applications of the gyroscopic principle.

Learning Outcomes:

Cognitive (Knowledge, Understanding, Application, Analysis, Evaluation, Synthesis)

On successful completion of this module you will be able to: 1. Develop the ability to recognise and identify elements of simple machinery and be able to classify and analyse the motion and forces associated with these elements. 2. Given a range of mechanisms develop the ability to analyse the motion and forces which are generated. 3. Given data on gear sizes and tooth numbers be capable of calculating inputs and outputs of simple and compound gear trains. 4. Given data on mass and acceleration of rotating and reciprocating bodies be capable of assessing balancing requirements. 5. Given data on geometry, mass and acceleration of cam components be capable of calculating motions and forces. 6. Demonstrate an ability to describe the motion of mechanical systems for differing levels of damping. 7. Recognise situations where Gyroscopic effects are important and must be accounted for in design calculations. 8. Working in groups, perform experiments in applied mechanics, analyse the results and identify sources of error.

How the Module will be Taught and what will be the Learning Experiences of the Students:

Normal lectures with tutorials and laboratory classes. Four group based laboratory assignments are carried out to analyse the characteristics of Epicyclic Gear Trains, Gyroscopes and Cam/Follower systems, in addition to balancing rotating masses.
