Hello again,
There have been a few changes at Motovated this month, with new projects
and in-house processes on the go. We would appreciate your feedback over
the next few months, as you are the people we are working for, to bring
you the best service and the best solutions for your projects. Please
email us any suggestions, anytime!
We have a couple of good brain teasers for you this month... Firstly, the
latest CAD package releases now come with a free limited capacity FEA
(Finite Element Analysis) tool, so we have put together a couple of
problems for you to solve. These kinds of problems often seem simple, but
can have some twists even when solving with a complete FEA package. So see
how you go solving them with your free version! Also below is the familiar
problem of beam bending, applied in this case to a bridge.
- Greg Morehouse (Managing Director)
Brain teaser #1: Is bigger always better?
Imagine two bridges are exactly alike except that the large bridge is two
times longer, and its structural members are two times thicker. Which
bridge can carry the most load, or are the bridges equally strong?
(Check the bottom of the
newsletter for the answer)
Opportunities at Motovated:
There are currently a couple of job positions available at Motovated for a
Mechanical Design Engineer and a Senior Engineer/Engineering Manager.
Follow the link for more info.
Staff changes at Motovated:
This month we say goodbye and good luck to Damien Murphy, who is off to
ECS Engineering. Damien has been with Motovated for two and a half years,
so we say a big 'thank you' for all the hard work he has put in and wish
him all the best for the future.
Brain teaser #2:
For those keen to test the new free FEA capability offered in their CAD
software, we have a couple of problems for you! If you would like to take
part, reply to this email and we will send you out the first two problems
as a pdf (a simple analysis and a harder analysis). You can also email us
for the analytical answers developed in Mathcad to compare your answers
against if you want, and we will post the answers and our method in the
next newsletter.
Upcoming training and events
COSMOS DesignSTAR 2006 update training is being offered in Christchurch
for anyone wanting to get to grips with the new user interface in the
latest release. Formal training is also available for anyone wanting to
brush up or expand their repertoire of FEA skills. We also offer onsite
training in most areas of FE Analysis. Give Greg a call on 03 382 5282 for
more information or to discuss your team's training needs.
Motovated 2006 Calendar...
Just a reminder, if you didn't a calendar and would like one, or know
someone who would like one, we still have some extras to give away...
Finally:
We hope you have all had a good start to the year, and look forward to
working with you over the coming months.
Best regards,
Greg and the team

Answer to brainteaser #1: The smaller bridge will carry the most load -
remember that bending moment varies linearly with span, but section
modulus is a cubic function of height, not thickness!
