Who’s talking?

• Mechanical Engineering Degree

• Commissioning Engineer, Large Steam Turbines

• Design and build drinking water systems

• Corporate Underwriter, Boiler and Machinery Insurance

• Able to change a fuse/reset breakers

Page 3: Building Bridges: Making the connection between Physics and Engineering

What’s the connection? 

• Engineering is the application of science

• Thinking creatively: from concept to form

• Working in a team

• Communication; team, calculation, report writing, audience

• Design, Build, Test and start again!

Today

1. Calculating and designing in groups with whiteboards.

2. Labs - Comparing recipe/confirmation labs and investigating ‘real’ situations

3. Design and Build

4. Trips - taking it outside

Re: Automotive crash on Monday 9th April, 2007 on 7th Line and Concession Road No. 6 just North of Highway 9 at or about 1.15pm.

Please analyse the diagram below and report to me by next Friday (court is set for the afternoon) giving your opinion of the speeds of the vehicles at the moment of impact. This intersection is a 4 - way stop and I would appreciate if you could give an opinion whether or not one or both of the vehicles stopped at the stop signs prior to proceeding through the junction. As there were no other witnesses to the accident other than the two drivers, I hope that you are able to provide an independent opinion, especially in view of the drivers’ conflicting reports. Hope this finds you well and not too busy with work. We are having terrible weather all this week with showers everyday. Let’s hope the summer comes soon. Thank you for you assistance in this matter Yours Truly Det. J Atherton
