What is Engineering? • Problem solving • Design • Innovation and Creativity • Application of math and science • Teamwork and Leadership • Communication • Professional
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? • 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
Innovation in... • Waste management • Transportation • Communication • Production of: food, tools, machinery • Human health • Space travel and exploration • Computers in everyday life
Traditional Engineering Programs • Civil Engineering • Mechanical Engineering • Electrical Engineering • Chemical Engineering
Non-Traditional Engineering Programs • Industrial Engineering • Environmental Engineering • Biological or Biomedical Engineering • Engineering Systems & Computing • Computer or Software Engineering • Water Resources Engineering • Aerospace Engineering
Engineering at Guelph • Biological Engineering (Biomedical or bio-process areas of interest) • Engineering Systems & Computing (Biomedical, software or mechatronics areas of interest) • Environmental Engineering • Water Resources Engineering
Design Engineering • Design courses starting in first year • First year - marble launcher • Second year - windmill powered battery charger • Third year - design of prosthetic arm • Fourth year design courses
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 completely under water, not touching the bottom
The Rules: • You may attach a device to the marble to suspend it in the water column • 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 mechansim • No explosives can be used
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 • Column 3 feet high • Water filled to within 2 inches of the top • A shallow sheet metal funnel will be attached to provide a greater entry radius (approx 3-4 feet) • Launch mechanism can touch the metal funnel but not the column or the water
OAC Requirements New Curriculum requirements OAC English ENG 4U 2 of OAC Physics, Chemistry and Biology 2 of PHYS, CHEM or BIOL OAC Calculus Advanced Functions and Introductory Calculus OAC Algebra & Geometry Geometry and Discrete Mathematics 1 additional OAC credit 1 additional grade 12 credit What do you need?
The Criteria • How long does the marble to descend to the bottom of the water column (longer is better) to a max of 5 min. • How expensive (cheaper is better) • Aesthetic appeal • Simplicity of design • Unique, innovative design
Brainstorming – the first step • No idea is a stupid or silly idea • Wild and crazy is good – suggest ideas without thinking too hard • One person record all of the ideas • No one is allowed to prove any ideas won’t work
What is Engineering? • Problem solving • Design • Innovation and Creativity • Math and science • Professional • Teamwork and Leadership • Communication
Solution 1 – Elastic launcher • Launching arm on an elastic band, potential energy by drawing back the arm launches the marble • Added prop to elevate the launcher • Adjustable to change the range of the launcher and improve accuracy
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 • 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 by potential energy, the can with the marble leaves the floor and rises to the column and tips the marble flotation device into the column
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 • 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 • Large balloon filled with water, diameter slightly less than the diameter of the column • Marble inside • 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 released gas, increases the balloon diameter, balloon gets stuck in column
The Winner • Solution 3 – Maximum suspension (5 min) • Second runner up – Solution 2 (4 min)
