2. At the end of this module, you will learn-
• Engineers’role in the society
• What is ethics?
• IESL code of ethics
• Case studies
• Engineering education standards
• Functions of professional bodies and IESL
• Functions of regulatory bodies and ECSL
• Administration knowledge required to practice as an engineers
• Financial knowledge required to practice as an engineers

3. • Who is an engineer?
• What is engineering?
• How engineering affected the lives of people?
• What is ethics?
• Why ethic is important for an engineer?

4. What are the qualifications required to follow
an Engineering course ?
• GCE A/L
Combined Mathematics
Physics
Chemistry

5. What did you learn from these subjects ?

6. Advanced Level Physics
Some of the theories,
• Electromagnetic Induction
• Maxwell’s theory
• Fleming’s theory
• When a conductor moves in a magnetic field an electric voltage
induced.
• When a current goes through a conductor, which is in a magnetic
field, a force is affected to conductor

7. What are the applications of these theories ?

8. Applications
• Generator
• Diesel - Driven by Diesel Engine
• Hydro - Driven by Hydro Turbines
It is an application of Electromagnetic induction theories.
• Maxwell Theory
• Flemign’s Right Hand rule
• Electric Motor
• DC Motors – Starting Motors /Traction Motors
• Induction Motors – Fan Motors
• Synchronous Motors – Compensators used in High Voltage Transmission
Principle of Motors
• Maxwell theory
• Fleming’s Left Hand rule

9. Theory vs Application
• Electromagnetic Induction – Theory
• Generator – application of theory
• Scientists discover theories
• Engineers apply theory and make devices and systems which will be
beneficial to human beings.

10. What is engineering ?
• Invent
• Design
• Construction (build)
• Operate and Maintain Complex systems
• Solving Complex problems
• Use science and mathematics knowledge

11. Competencies required to be an engineer
• Theory Knowledge – From the Engineering degree course
• Basic Practical Skills and Approach - Internship ( in plant training )
• Advanced Practical skills and approach -working in the field
• Leadership and Communication -working in the field
• Skills in Cost effective approach - working in the field

12. Definition of Engineers
• Engineering is the application of science and maths to solve
problems. Engineers figure out how things work and find practical
uses for scientific discoveries. Scientists and inventors often get the
credit for innovations that advance the human condition, but it is
engineers who are instrumental in making those innovations available
to the world.

13. Engineer and Society
• Everything done by engineers is affected to society.
Eg.
Construction of a new road
Widening a road
Construction of a new power station
Erection of an antenna tower

14. Engineer’s role in the industry

15. Introduction to IESL

16. Introduction to Engineering Council Sri Lanka
(ECSL)

17. Basic Codes in Engineering Ethics
 Practice Sustainable Engineering
Be committed to sustainable management of resources
Minimize adverse environmental impacts to
Protect both present and future generations.
 Public Goodness is Paramount
Ensure health, safety, welfare of public.
Proper utilization of funds & resources. Respect the Law.
 Uphold Professional dignity Uphold & enhance the honour, integrity and dignity of the profession
 Build Reputation on Merit Build reputation on merit and shall not compete unfairly
 Limit to area of competence Perform services only in the area of competence
 Serve benefactors faithfully with no conflict to
other principles
Apply skills & knowledge in the interest of employer or client, in professional
matters, as faithful agents or trustees,
with no conflict with other principles and the general public interest
 Speak out objectively & truthfully
Give evidence, express opinions or make statements
in an objective and truthful manner.
 Continuously develop knowledge and skills
Continue Professional Development throughout the career
Actively assist/encourage engineers under their direction to advance their
knowledge and experience.
