Skip to 0 minutes and 9 seconds SPEAKER 1: Well, that’s it. The course is nearly over.
Skip to 0 minutes and 13 seconds SPEAKER 2: We hope you’ve enjoyed exploring engineering mechanics, discovering a way of thinking and developing new skills. We’ve covered a lot of ground with our experiments, analysis, and design.
Skip to 0 minutes and 27 seconds SPEAKER 1: And, of course, we have highlighted the engineering mindset.
Skip to 0 minutes and 31 seconds SPEAKER 2: In week one, we looked at what a load does to an elastic element. And we saw the difference between static and dynamic conditions.
Skip to 0 minutes and 40 seconds SPEAKER 1: In week two, we used free-body diagrams to reveal forces. We saw how forces add and checked it out with force transducers.
Skip to 0 minutes and 49 seconds SPEAKER 2: Equilibrium appeared. The design task highlighted engineering responsibility.
Skip to 0 minutes and 56 seconds SPEAKER 1: In week three, we explored twisting effects.
Skip to 1 minute and 0 seconds SPEAKER 2: They introduce a new equilibrium equation.
Skip to 1 minute and 4 seconds SPEAKER 1: We saw how to draw FBDs for rigid bodies and used them with equilibrium to solve practical problems.
Skip to 1 minute and 11 seconds SPEAKER 2: It was a magic moment.
Skip to 1 minute and 14 seconds SPEAKER 1: In the rest of the course, we looked at the different types of loads we might need to include on our FBDs.
Skip to 1 minute and 21 seconds SPEAKER 2: In week four, it was gravity, weight, and where it acts. We found the centre of gravity. It is another application of moments.
Skip to 1 minute and 32 seconds SPEAKER 1: In week five, it was friction. Sometimes we want less friction. Sometimes we want more. We saw how a rough-and-ready theory is applied in practice.
Skip to 1 minute and 44 seconds SPEAKER 2: In week six, it was wind loads. And that introduced a beautiful equation. We applied the analysis to vehicles.
Skip to 1 minute and 54 seconds SPEAKER 1: To maintain steady motion of a vehicle, we must overcome drag from our three sources– hill climbing gravity, rolling resistance friction, and air resistance wind.
Skip to 2 minutes and 6 seconds SPEAKER 2: And we saw how to find the power that a vehicle needs for a specified performance.
Skip to 2 minutes and 12 seconds SPEAKER 1: In week seven, we started looking at dynamics, accelerations, but mostly that will be for another time.
Skip to 2 minutes and 19 seconds SPEAKER 2: Now, whatever you choose to do in future, you will have begun to see the world through engineers’ eyes.
Skip to 2 minutes and 27 seconds SPEAKER 1: Maybe you have been changed forever.
Through Engineers' Eyes - final thoughts
Congratulations on reaching the end of the course!
The concept wheel shows how the last four weeks fit together. The final short video reviews the whole seven weeks. The chances are that you have developed engineers’ eyes.
Week 7 concept wheel (Click to expand)
This is a wrap up week combined with a look forward to what you could study next.
In the experiment for this, the final week, accelerations were present. So we needed Newton’s second law - the heart of Dynamics - and we needed to understand motion. There’s so much more, but we have come to the end of our course, so deeper study will have to wait.
On the other hand, we’ve covered a lot of Statics; how to calculate unknown forces for a wide range of 2D statics conditions and a few dynamics ones too.
We hope that you have enjoyed learning about Engineering Mechanics through experiment, analysis and design, and that you are getting used to your ‘engineers’ eyes’.
We’ve enjoyed following your discussions and other contributions. Now we would like your overall impressions of the course in the comments section.
If this course has inspired you to consider further academic study in the field of Mechanical Engineering check out the UNSW Mechanical and Manufacturing Engineering website for more details.
We wish you all the very best.
