THE TACOMA NARROWS BRIDGE COLLAPSE
The Tacoma Narrows bridge, at 5959 feet long, spanned Puget Sound’s Tacoma Narrows Strait. It was the third longest suspension bridge existing in 1940 and was designed to be the most flexible. During construction, it earned the nickname of "Galloping Gertie" because of its motion in the wind. It opened to traffic on July 1, 1940 and dramatically collapsed during a windstorm, only four months later, on November 7. What happened ?
Aerodynamic forces were not something that bridge designers considered at the time the Narrows bridge was constructed. Today these forces, caused by winds impacting on a structure, are well know and are a factor in the design process. Oscillations, known as aeroelastic flutter, were induced by winds of about 40 mph impacting the bridge. The bridge decks lengthwise center section remained steady, while the outer sections oscillated about it in a twisting fashion. At one point, one sidewalk was 28 feet above the one on the opposite side. As might be expected, this movement caused severe structural damage which eventually resulted in collapse. The 6 million dollar damage in 1940 dollars equates to about 1 billion dollars today. To view the collapse click here.
The first day of the month 0000Z through the last day of the month 2400Z
Just make ALL these words from calls of stations you work subject to the General Challenge Rules. (Any spaces in the phrases should be ignored. For example the challenge phrase "INVERTED V ANTENNA" should be treated as if it is the single word "INVERTEDVANTENNA.")
5959 FEET LONG
TACOMA NARROWS STRAIT
NOVEMBER 7 1940
The 87 total letters and numbers contain these 24 different letters and numbers : A B C D E F G I L M N O P R S T U V 1 4 5 7 9 0
You can use each letter in a call TWICE. For example you could use K3WWP for 2 K's, 4 W's, and 2 P's.
Subsequent QSO's with the same station cannot be used for additional letters. For example, no matter how many times you work K3WWP, you can only use his call for 8 of the letters in the words.
See General Rule #5 for more details on what callsign letters can be used.
If you need some help with your alphabet challenge record keeping take a look at our Alphabet Tutorial page for everything from some great pencil & paper methods to fully computerized tools.
A certificate and Participation Point go to everyone making all the words and submitting their report before the deadline.
A Participation Point goes to everyone making at least 1, but not all the words and submitting their report before the deadline.
A choice of an item made by master woodworker Gregg WB8LZG as shown on our prizes page here goes to someone selected via a random drawing from all who participate and submit a report for this month's challenge. A person can only win once, then they become ineligible for future drawings.
For your report, list the words you made and the station used for each letter in the word. The number of stations listed must be the same as the number of letters in each word, even though you use the same station for more than one letter as in:
WORD - K3WWP N2OD WA8REI N2OD
NEXT - NF8M W8REI N8XMS K9EYT
(Note how N2OD is listed for both the O and D.)
You may also include comments about the challenge. Please preface any comments you want posted with "SOAPBOX:" so we will know what you want posted and what is private.
