3. 1a.3 SYMBOLIC NOTATION AND
ENGINEERING
• a writing system used for recording concepts
• uses symbols or symbolic expressions
• these symbols have denoted numbers, shapes,
patterns and change

4. Symbolic Notation’s relevance to
Engineering in time:
● (a.) FAMILIARITY
It represents aspects of
thought and actions in
graphical form which are
familiar to students of all
engineering disciplines.

5. Symbolic Notation’s relevance to
Engineering in time:
● (b.) EMPIRICISM
It constitutes a practical way
of depicting complex
processes of central
importance to the theory and
practice of engineering.

6. Symbolic Notation’s relevance to
Engineering in time:
● (c.) HEURISTICS
It suggests useful and
efficient means of organizing
and exploring the historical
progression and
contemporary context of
engineering.

7. 1. Force diagrams
Such notation can take many
forms, for example:
2. Circuit representations 3. Vector notation
4. Electromagnetic
field depictions
5. Phase-plane
projections

ESSENTIAL CONCEPTS
N(t) represents nature as
the basic starting point of
a most relevant
progression.
a. Nature constitutes
the resource of basic
materials

9. examples:
stone, wood, fiber, water,
metal,petroleum, ...

10. 1a.4
ESSENTIAL CONCEPTS
N(t) represents nature as
the basic starting point of
a most relevant
progression.
b. Nature embodies the
physical phenomena of
foundational
importance to the
theory of engineering

11. examples:
hardness, diffusion,
heat, elasticity,
friction, turbulence, ...

12. 1a.4
ESSENTIAL CONCEPTS
N(t) represents nature as
the basic starting point of
a most relevant
progression.
c. Nature possesses
autonomous
dynamical features

13. examples:
earthquakes, water cycle,
hurricane winds,
flash floods, ...

14. 1a.4
ESSENTIAL CONCEPTS
a. A device may be an artifact,
constructed or adapted but
invariably
based on considerations of
synthesis.
D(t) identifies engineered
devices – the ingenious and
useful human- made objects.

15. examples:
• hardware object-
a tool, prosthesis, sensing instrument
• cognitive object-
strategic idea, optimal process,
action program

16. 1a.4
ESSENTIAL CONCEPTS
b. A device may be
associated with a commodity
providing selected
functions:
D(t) identifies engineered
devices – the ingenious and
useful human- made objects.

17. examples:
• projection of information-
book, clock face, monitor display
• means of transportation-
wagon, parachute, aircraft
• serve the need of sustenance-
water pipe, cutlery, flour mill
• supply entertainment-
guitar, video, dynamic art
• provide physical comfort-
furnance, lawn chair, mosquito spray

18. 1a.4
ESSENTIAL CONCEPTS
c. A device may also be
characterized as a
synthesized object which
engages, stimulates and
enables its makers and
users.
D(t) identifies engineered
devices – the ingenious and
useful human- made objects.

19. 1a.4
ESSENTIAL CONCEPTS
d. A device may further be
viewed as a convenient
unit of engineering
theory and practice.
D(t) identifies engineered
devices – the ingenious and
useful human- made objects.

20. 1a.4
ESSENTIAL CONCEPTS
(a) Definition
Engineering represents creative
thought and skilled actions
associated with the use or
adaptation of natural materials
and natural phenomena.
With N(t) and D(t) so
characterized, it is evident that
engineering E(t) constitutes
the central and uniting
connection in the progression
from N(t) to D(t).

21. 1a.4
ESSENTIAL CONCEPTS
(b) Corollary I
Engineering may be interpreted
as the rational activity
concerning specifics of how to
make devices and how they
might be made better.
With N(t) and D(t) so
characterized, it is evident that
engineering E(t) constitutes
the central and uniting
connection in the progression
from N(t) to D(t).

22. 1a.4
ESSENTIAL CONCEPTS
(c) Corollary II
Engineering constitutes the
domain of thought and
action which uses what is to
create what may be.
With N(t) and D(t) so
characterized, it is evident that
engineering E(t) constitutes
the central and uniting
connection in the progression
from N(t) to D(t).
