Major functions of an Engineering
SocietyEngineering societies are much more that
just social organizations. They perform many
important functions within the engineering
profession.There are five key functions
Lecture 5 EGR 120 Introduction to
Engineering
1. The sharing of ideas

• Transactions or journals are published in very
  specific areas to keep engineers informed about
  new developments and research within their area
  of expertise.
• The journals are very specific. For example,
  IEEE alone has around 70 different journals, with
  titles including
• The IEEE Transactions on Applied
  Superconductivity
• The IEEE Transactions on Circuits Systems for
  Video Technology
• The IEEE Transactions on Image Processing
• Why are journals important?
• Societies typically publish less technical
  magazines as well, such as IEEE Spectrum, which
  is aimed toward all engineers in a given
  discipline.

2. Development of standards

• Why are standards important?
• Some standards are familiar to the average
  person, while others are familiar only
  professionals within a given area.
• Examples
• IEEE 1754 Standard for 32-bit Microprocessor
  Architecture
• IEEE 488 Bus
• SAE standards for viscosity of oil (such as SAE
  10W40 motor oil)
• ASME standards for pipe sizes, bolt sizes, thread
  sizes, etc

The Mini Baja car is the oldest member of the
"Car Factory," which is one of the Student
Involvement Programs of the Virginia Tech
Department of Mechanical Engineering. The Mini
Baja project and competitions are sanctioned and
supervised by the Society of Automotive
Engineers. The rules specify that either a new
car must be designed and built each year or a car
from an earlier year must be significantly
modified. The Virginia Tech approach has been for
the team to design and build a new car every
year, keeping the best features and resolving
problems identified with the cars of previous
years, and trying new ideas, which are brought to
the project by each new team. The Virginia Tech
Mini Baja team is made up of students, primarily
seniors in mechanical engineering, although
students at any academic level and from any major
are welcome to participate.

Virginia Tech Formula SAE
The engine team is responsible for designing the
complete engine package. Our engine is a 600cc
Honda F2. The engine team designs the intake,
turbocharger, injection, cooling, and exhaust
system. This year, the engine team is considering
incorporating an intercooler with the
turbocharger, and using some parts from the Honda
F3 engine. The engine team has yet to blow
anything up! The suspension guru has been hard
at work concocting yet another suspension system
to glue this years car to the track. The
suspension team is very busy analyzing all of the
components and optimizing their designs. With
weight being their main concern, they are very
busy removing as much mass as possible from these
systems. Our chassis has been designed to
support the suspension and drivetrain components.
The key to a winning chassis is its structural
rigidity. This year's car will once again be a
tubular spaceframe constructed of 1020 mild steel
with 4130 chromemoly roll bar.

Lecture 5 EGR 120 Introduction to
Engineering
What is an autonomous vehicle? An autonomous
vehicle is a mobile robot that can navigate and
drive completely by itself, with no human
intervention. The vehicle uses sensors such as
cameras and lasers to gather information about
its environment. An on-board computer "brain"
processes the data and determines where the robot
can travel safely. The computer then sends
commands to drive and steering motors to propel
the vehicle. Why bother with autonomous
vehicles? Autonomous vehicles are the machines of
the future. The US government is mandating
programs for the development of intelligent
transportation systems, including vehicles that
drive autonomously. Companies are also
researching other uses for autonomous vehicles,
including coal-mining carts and vacuum cleaners
that do not require a human operator.

The Hybrid Electric Vehicle Team of Virginia Tech
(HEVT) was formed in early 1994 to prepare a
design proposal for the 1995 Hybrid Electric
Vehicle (HEV) Challenge. This competition
involved converting a stock Dodge Neon to an HEV.
The team's proposal was accepted and the team
converted their Neon accordingly, finishing fifth
in a class of twelve. This year The Hybrid
Electric Vehicle Team of Virginia Tech (HEVT) has
accepted a brand new challenge. This year's task
is much larger than years past. For the year
2000, HEVT is attempting to create the world's
first ever Hydrogen Fuel Cell powered sport
utility vehicle (SUV). And not just any SUV, one
of the largest ever built. This November we take
delivery of a 2000 model year Chevrolet Suburban.
Our goal, turn it into a Zero-Emissions Vehicle
that operates equally as good or better than
stock, including the ability to tow a combined
weight of 13,000 pounds up a 5 grade at 55 miles
per hour. And all this before June 1st, 2000.

A total of one and one half points separated the
number one and two teams this year, and Clemson
leaves Melbourne, FL, with its first national
title. Our website provides many interesting
stats, scoring breakdowns, highlights, reviews
and pictures from previous national competitions
not just for Clemson, but for all schools. Links
are provided from our site to other schools'
canoe sites as well as to the websites for ASCE
and Master Builders (official organizer and
sponsors of the National Concrete Canoe
Competition). You will not find a more complete
and inclusive concrete canoe website anywhere
else. We were recognized in the "WebWatch"
section in the April issue of Popular Science
Magazine. If you have the magazine, you can find

International Submarine Races TM
The first human-powered International Submarine
Race TM (ISR) was held in 1989 off Riveria Beach,
Florida and drew 17 boats. The race grew to 35
boats in 1991 and 44 contestants for the 1993
race off Fort Lauderdale, Florida. The 1995 event
(the first ISR indoors) at the Naval Surface
Warfare Center (David Taylor Model Basin) drew 11
entrants. The 1997 event at David Taylor drew 16
boats. Each team must develop a one or
two-person "Wet" submarine. Two-person subs must
have one person providing the propulsion and the
other navigating and steering. Both crew members
breathe SCUBA from the air supply carried aboard.
Each sub is unique, designed from "scratch," and
relies upon novel techniques for propulsion and
guidance.

1998 Knight Mine Hardware Competition
The goal of the Hardware Competition is to design
and build an autonomous, robotic car to shut off
four optical switches located in the corner of an
8' by 8' playing surface. The car must avoid
"mines" on the playing surface while sensing for
the infrared signal defining the current switch
location. The mines come in two forms 1) There
are eight fixed mines which are 8" by 8" square
and have a predefined location. 2) There is one
randomly located mine, centered at an
intersection of the grid lines painted on the
playing surface. A coil that carries a specified
signal will surround this mine. The car must
accomplish this task in the shortest amount of
time possible.

TCC Engineering Club
CANstruction is a nationwide competition
sponsored by the National Society of Professional
Engineers (NSPE). The goal of the competition is
to build structures out of canned and
pre-packages food items which will later be
donated to local food banks. The TCC Engineering
Club has competed in this event since
1997. CANstruction 98 TCC Engineering students
built a 14 tall, 3000 lb model of the Hatteras
Light House using 2600 cans of food. The
lighthouse featured an interactive rotating
beacon and a foghorn. The lighthouse was on
display in the Virginia Marine Science Museum for
about 6 weeks.

CANstruction 99 TCC Engineering students built a
10 tall model of the NASA Space Shuttle using
4000 cans of food. The space shuttle included an
interactive electronic Space Shuttle Quiz on
space shuttle trivia and an interactive control
where visitors could see a large countdown
display and hear a countdown sequence of an
actual launch. The CANshuttle was on display
in Pembroke Mall for two months.
