Intro: 1
What’s in ENG2000?
• Split into two parts …
 Materials Science & Engineering
 Management and Economics of Engineering Design Projects
• Intended to cover technical material of relevance
to all engineers
 part of the engineer’s “general knowledge” of how the world
works
 tools for working in engineering
• Also contains a design and construction project
 predict performance of your design before demonstrating it
 meet cost and performance targets

Materials – the global perspective
• The characteristic that defines humanity is not
the use of tools but the understanding of
materials
• Properties of interest include(d):




strength & weight
sharp edges
insulation
workability
• It is discoveries of “new” materials that have
shaped history




flint & glass
soft metals (copper, tin, lead)
alloys (bronze)
iron

Ok – but I still want to know why a
knowledge of materials is relevant to me!
• We all use computers every day ...
• Let’s see how many materials we need to use a
computer ...
 Chips:
crystalline Si, SiO2, poly-Si, aluminum, boron & phosphorus doping,
adhesives, ceramic package,
• all materials & chemicals required to make all of the above
•
 Other electronics:
•
quartz, copper, carbon, dielectrics, plastic & ceramic insulators, circuit
board (fibreglass), solder (lead & tin), ferrite transformer core, goldplated electrodes
 Disk drive:
•
ENG2000: R.I. Hornsey
magnetic motor components, magnetic films
Intro: 9
 CD ROM:
•
optical lenses, laser components, reflective cd film
 Monitor:
•
glass, phosphors, tungsten filament
 Communications:
•
Fibre-optic cable, transmitter, receiver, amplifiers
 Mechanical:
•
plastics, steel, copper, aluminum
 Plus:
all the materials needed to generate and transmit power
• all the materials required by telephones
• all the materials for building & furniture, ventilation etc!
•

Mechanics of materials
• The previous examples were primarily
‘electronic’, but mechanical structures are
equally important
• An elementary knowledge of structures – the
‘mechanics of materials’ – is vital to all engineers
 computer engineers often end up designing control systems
for complex mechanical systems
•
cars, space shuttle, flexible robotic systems
 for space engineers, the mechanics of the satellite or space
vehicle are critical to the design of all systems
 the expertise of geomatics engineers is frequently used for
locating and monitoring engineering structures
 mechanical properties of materials – and how to improve
them – are the domain of the engineering physicist

Purpose of ENG2000 pt.I
• Each material and structural design is used
because of its specific properties
• In order to design and use these materials
effectively – which makes us humans superior to,
say, my cat – we must know what these
properties are and how to control them
• Therefore, we need to understand the factors that
determine these properties
• Then we need to know how to optimise use of the
materials in engineering applications

Intro: 13
Fall Term
• Team Project (15%)
 design and analyse a crane structure to carry a load of
1,800kg (equivalent to a Lexus SUV) at a height of 50m, and
at a horizontal distance of 25m from the base.
• Exam (35%)
ENG2000: R.I. Hornsey
Intro: 14
Winter Term Project (50%)
• In teams of four, design, construct and
demonstrate a flying vehicle to travel at least
10m. The total cost of the project components is
limited to CDN$10 (including any failed designs).
 Prizes will be awarded to the team landing closest to a target
at 15m, to the lightest machine, and to the most aesthetically
pleasing entry.
 Requirements will include: a proposal, a progress report, a
final report and presentation, and the demonstration.
• Emphasis will be placed on the design process,
calculations (rather than trial and error), and
predictions of performance, as well as project
planning and documentation.
• Full rules and requirements to be announced.
