ABRIDGED COURSE SYNOPSIS

 

The aim of the course will be to develop knowledge and understanding the principles of engineering science. The topics covered in the course will provide a scientific proof for many of the processes carried out elsewhere on the course and also an appreciation of the functions of the varied types of machines, which will be used.

 

The relationship between the acquired theoretical knowledge and the practical application is developed by the study of engineering applications, materials used in industry and by specific laboratory experiments.

 

Documentation and analysis of these laboratory experiments will develop a conceptual understanding of the basic principles and practical proofs of some theoretical aspects of the course.

 

 

COURSE AIMS AND OBJECTIVES

 

The student teacher should be able to:

                                i.      Understand the basic principles involved in Engineering Science;

                              ii.      Demonstrate a knowledge about: the effects of force in nature; the usage of levers and linkages; the concept of statics; the principles of motion; the basic law of potential and kinetic energy; the first law of heat; the basics of friction; gearing mechanism; the basics of hydraulics and the various types of corrosion;

                            iii.      Demonstrate an advanced level of understanding of engineering principles to enable him/her to teach a technology subject to senior level.
