6.
Engineering is the application of science
and mathematics to solve problems

7.
• A person who has scientific training and who
designs and builds complicated products,
machines, systems, or structures Engineers are
problem solvers
• They have good grasp of fundamental physical,
chemical and mathematical laws.
• They consider factors like sustainability,
efficiency, cost, reliability and safety.
• They are dedicated to lifelong learning and
service to others.

8.
Engineering Work is all around
you:
• Heating, Air-conditioning and ventilating
systems in home- Mechanical Engineers
• Power plants and power stations- Electrical &
Mechanical Engineers
• Towel Used for morning shower- Agricultural,
Manufacturing,
• Chemical, Petroleum, Civil and Mechanical
Engineers
• Other examples: Milk kept in refrigerator, the
car you are about to drive

9.
What Engineers do?
• Engineering Products: Cars, Computers, aircraft,
clothing, toys, home appliances, surgical
equipment, heating and cooling equipment, health
care devices, tools and machines etc..
• They supervise construction of buildings, dams,
highways and mass transit systems and
construction of power plants
• They play major role in the design and
maintenance of a nation’s infrastructure including
communication systems, public utilities and
transportations.

10.
What Engineers do?
• They continuously develop new, advanced
materials to make lighter and stronger products.
• They bring ways of increasing crop, fruit and
vegetable yields along with improving the safety
of food products.
• Engineers work as sales representatives of
products, sales and customer support,
maintenance of various products and machines.
• They work in the departments of agriculture,
defense, energy and transportations.
• Some Engineers work for the National

Common Traits of Good Engineers
• Engineers are problem solvers.
• Good engineers have a firm grasp of the
fundamental principles of engineering, which
they can use to solve many different problems.
• Good engineers are analytical, detailed oriented,
and creative.
• Good engineers have a desire to be lifelong
learners. For example, they take continuing
education classes, seminars, and workshops to
stay abreast of innovations and new
technologies.

12.
Common Traits of Good Engineers
• This is particularly important in today’s world
because the rapid changes in technology will
require you as an engineer to keep pace with
new technologies.
• Moreover, you will risk being laid off or denied
promotion if you are not continually improving
your engineering education.

13.
Common Traits of Good Engineers
• Good engineers, regardless of their area of
specialization, have a core knowledge that can
be applied to many areas.
• Therefore, well-trained engineers are able to
work outside their area of specialization in
other related fields.
• For example, a good mechanical engineer with
a well rounded knowledge base can work as
an automotive engineer, an aerospace
engineer, or as a chemical engineer.

14.
Common Traits of Good Engineers
• Good engineers have written and oral communication skills
that equip them to work well with their colleagues and to
convey their expertise to a wide range of clients.
• Good engineers have time-management skills that enable
them to work productively and efficiently.
• Good engineers have good “people skills” that allow them
to interact and communicate effectively with various
people in their organization. For example, they are able to
communicate equally well with the sales and marketing
experts and their own colleagues.

15.
Design / Manufacturing Interface
• Engineers are required to write reports. These
reports might be lengthy, detailed technical
reports containing graphs, charts, and
engineering drawings, or they may take the
form of brief memoranda or executive
summaries.
• Engineers are adept at using computers in
many different ways to model and analyze
various practical problems.
Common Traits of Good Engineers

16.
Common Traits of Good Engineers
• Good engineers actively participate in local
and national discipline-specific organizations
by attending seminars, workshops, and
meetings. Many even make presentations at
professional meetings.
• Engineers generally work in a team
environment where they consult each other to
solve complex problems. They divide up the
task into smaller, manageable problems
among themselves; consequently, productive
engineers must be good team players.

17.
Common Traits of Good Engineers
• Good interpersonal and communication skills
are increasingly important now because of the
global market.
• For example, various parts of a car could be
made by different companies located in
different countries.
• In order to ensure that all components fit and
work well together, cooperation and
coordination are essential, which demands
strong communication skills

18.
Expected Educational Outcomes
from an engineering graduate:

19.
• The starting salaries of engineers are significantly higher than
those of bachelor’s-degree graduates in other fields. The
outlook for engineering is very good.
• Good employment opportunities are expected for new
engineering graduates during 2010 –2018.
• Most engineering degrees are granted in electrical,
mechanical, and civil engineering, the parents of all other
engineering branches.
• In the year 2008, engineers held 1.6 million jobs

Accreditation Board for
Engineering and Technology
• Over 300 colleges and universities in the
United States offer bachelor’s-degree
programs in engineering that are accredited by
the Accreditation Board for Engineering and
Technology(ABET).
• ABET examines the credentials of the
engineering program’s faculty, curricular
content, facilities, and admissions standards
before granting accreditation.

23.
According to ABET, accredited engineering
programs must demonstrate that their
graduates, by the time of graduations, have
• an ability to apply knowledge of mathematics, science,
and engineering;
• an ability to design and conduct experiments, as well as
to analyze and interpret data;
• an ability to design a system, component, or process to meet
desired needs;
• an ability to function on multidisciplinary teams;
• an ability to identify, formulate, and solve engineering
problems;
• an understanding of professional and ethical responsibility;
• an ability to communicate effectively;

24.
According to ABET, accredited engineering
programs must demonstrate that their
graduates, by the time of graduations, have
• the broad education necessary to understand the impact of
engineering solutions in a global and societal context;
• a recognition of the need for and an ability to engage in
lifelong learning;
• a knowledge of contemporary issues; and
• an ability to use the techniques, skills, and modern
engineering tools necessary for engineering practice.
