What is Engineering

1
What is Engineering?

• Problem solving
• Design
• Innovation and Creativity
• Application of math and science
• Teamwork and Leadership
• Communication
• Professional

2
What do Engineers do?

• Work in industry, government or consulting
• Develop surgical instruments
• Design municipal infrastructure (water
  distribution lines, water treatment)
• Remediate a contaminated site
• Design a robotic systems for a production line in
  a factory

3
Engineer or Scientist Whats the difference?

• Science understand concepts, learn about theory
  and principles, have expertise
• Engineering applies principles of math and
  science to solve real-life problems
• Engineers and scientists often work together as
  part of a team
• Engineering is a profession P.Eng

Robotic Arm Demonstration

The Mission

• Design, build and test a device to transport a
  marble from less than a foot off the floor into a
  column of water
• Slow the descent of the marble to the greatest
  extent possible
• Maximum time under water, not touching the bottom

13
The Rules

• You may attach a device to the marble
• You may not change the marble
• Human energy can only supply potential energy to
  the launch mechanism
• If you add something to the water, it must be
  added with the marble
• No explosives can be used

14
More Rules

• Made entirely by recycled materials
• Constructed by the group
• Total equivalent cost less than 50
• Safe for a nine year old to use
• No animals may be used/harmed in the design

15
The column

• Column 4 feet high
• Water to within 2 of the top
• A shallow sheet metal funnel will be attached to
  provide a greater entry radius
• Launch mechanism can touch the metal funnel but
  not the column or the water

16
The Criteria

• How long does the marble take to descend to the
  bottom of the water column
• Cost (cheaper is better)
• Aesthetic appeal
• Simplicity of design
• Unique, innovative design

Solution 1 Elastic launcher

• Launching arm on an elastic band, potential
  energy by drawing back the arm launches the
  marble
• Adjustable to change the range of the launcher
  and improve accuracy

19
Solution 1 Cork floater

• Marble attached to cork buoyant forces
  counteract the weight of the marble
• Flat piece of cork acts to provide drag in the
  water

20
Solution 2 Weight pulley on a ramp

• Weight (pop bottle filled with nails) attached by
  string to ½ popcan holding the marble flotation
  device over a pulley (old inline skate wheels)
• As weight falls, the can with the marble leaves
  the floor, rises to the column and tips the
  marble device into the column

21
Solution 2 Oil capsule

• Spherical capsule filled with canola oil (lighter
  than water)
• Fishing weights and paperclips to balance weight

22
Solution 3 Counter-weight lift device

• Elevator type lift wooden structure with a
  angled platform
• Free weights attached by string to the platform
• Once released from the top of the structure, the
  weights fall, and the platform rises, releasing
  the flotation device into the column

23
Solution 3 Water balloon

• Marble in a large water balloon, diameter
  slightly less than the diameter of the column
• Attached to a PVC pipe capsule containing
  alka-seltzer
• When balloon is released, water leaks into
  capsule through a drilled hole
• Reaction with alka-seltzer releases gas,
  increasing the balloon diameter
