Magic Marketing

From: Lee Hines
To our one & only Magic Man,
In the never ending quest for brevity in our communication, I modestly propose the following  shorter version of “Magic Dongle” might be appreciated by all involved users:
Simply transpose the first two letters of each word to form the word…
wait for it…’MANGLE’.??

Thank me later, I knew you would like it.
Ciao,
Leeper


Dear Mr Hines

Thank you for your letter applying for a job in the Magic Timers marketing  dept.
I do not think you are suited to this job.  It is perhaps better you keep your day job.
If you wish to continue along a marketing or stand up comedy track I suggest that you study the writings of Anselmo Zeri, CHE, Allard , Fantham, etc

Bending the curve – SEN 2758

From:hermann andresen

Roger,
My experience with curved dihedral echoes my structural prof’s assessment that a small load on a curved beam can result in a larger or smaller curve, while with a straight beam it takes a much higher force to get any measurable deflection at all.

How about F1D?
How about bracing?

Hermann


Editor’s note
The article in FFn is by Ian Kaynes and is more concerned with the process of building a curved dbox wing.  It relates to Ian’s F1E experience . Seeing Ian is a real engineer in the aeronautical field I would expect it to handle the loads.

And F1E and F1D are very different and very specialized fields while not a practitioner of either I would not expect bracing to apply to E.
