In China

beijingI am on a short trip to China and if you are reading this post then it means that I have been unable to access my blog from China.  Normal service should resume next week.  The picture came from a previous visit!

100 Everyday Engineering Examples

bookletsSTOP PRESS – more than 100 Everyday Engineering Examples published in more than 40 lesson plans on a new webpage.

I have been including 5E lesson plans as part my recent posts.  These lesson plans are primarily for people teaching first-year engineering undergraduates, which is pulling me away from the intended focus of this blog. So, I have decided to publish all of the lesson plans that I have written & edited on a separate page.  There are more than 100 Everyday Engineering Examples in the more than forty lesson plans.  If that is not enough Everyday Engineering Examples then you can find more at ENGAGE

Now back to Realizing Engineering – we live in an almost entirely engineered world. Engineers, as a profession, are so good at their job that most people are unaware of their influence on society.  Look around you. Engineers will have designed the machines and transport infrastructure to supply most of what you can see as well as what you are probably sitting in and on.

The Royal Academy of Engineering has produced an ebook to expand on this theme of ‘Engineering in Society’ for first year engineering undergraduates but I think its suitable for anyone considering a career in Engineering.

Singing in the rain

Followers of this blog might have deduced that I live within sight of the sea, which means that it is nearly always windy.  After a rain storm the streets of the city are usually littered with broken umbrellas.  I suspect that most of these belong to the many tourists that visit Liverpool, because local residents know that the wind will wreck any umbrella that you are brave enough or foolish enough to put up.

It is relatively straightforward to estimate the forces involved in holding an umbrella up in a gale by using control volume analysis.  The lesson plan below includes this Everyday Engineering Example together with two more control volume analyses.

The title of the posting is pretty tenuous this week: Gene Kelly sings ‘Singin’ in the rain’ without an umbrella in the film of the same name, see – well its difficult to be creative all of the time, or even some of the time!

See also the Everyday Engineering Examples page on this blog for more lesson plans and more background on Everyday Engineering Examples.

What is Engineering?

Engineering turnover in the UK was £1.1 trillion (for the year ending March 2012) which was 24.5% of UK turnover.  So clearly engineering is big and important to the economy of industrialised countries.  But what it is?  That’s a harder question to answer!  In 2013 almost two-thirds of the public could cite the engineering development of the last 50 years that has had the greatest impact on them – that compares with slightly more than one-third in 2010 so more people are beginning to recognise engineering when they see it.  Can you cite the engineering development that has had the greatest impact on you?  If so, post a comment (use the ‘Leave a reply’ box at the bottom of the page).

What is Engineering? As well as being the title of this post it is also a website that attempts to answer the question. You will find the classical answers there and elsewhere, i.e. that engineering is about taking the resources able in nature and converting them into products (e.g. buildings, computers, medical devices and planes) and services (e.g. water, electricity and communications) for society.  Engineers are problem-solvers who communicate and organise the implementation of solution which might be how to create a zero emission car or a carbon-neutral public building.  The best engineers look for elegant solutions so I rather like the no.2 definition that you get when you Google the question, i.e. ‘the action of working artfully to bring something about’.
