what do engineers do
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
engineer or scientist what s the difference
Engineer or Scientist – What’s 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

What do you need?
design engineering
Design Engineering
  • Design courses starting in first year
  • First year - marble launcher
  • Second year - windmill powered battery charger
  • Third year - design of soccer playing robots
  • Fourth year design courses
the mission
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
the rules
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
more rules
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
the column
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
the criteria
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
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
solution 1 cork floater
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
solution 2 weight pulley on a ramp
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
solution 2 oil capsule
Solution 2 – Oil capsule
  • Spherical capsule filled with canola oil (lighter than water)
  • Fishing weights and paperclips to balance weight
solution 3 counter weight lift device
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
solution 3 water balloon
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
the winner
The Winner
  • Solution 3 – Maximum suspension (5 min)
  • Second runner up – Solution 2 (4 min)
