Collier Smith's Solution to the Puzzle |
1. Closing the arch of Sydney Harbor bridge, sometime before 10 pm on 19 August 1930. (That was 2 months after mid-winter, so apparently the closure would have been completed in the dark.) 2. The centerline of the lower main arch beam is 18 meters lower than the top of the arch, at 134 m. above mean sea level (aMSL) (see drawing/poster below). Hence, the two workers standing on that beam would be standing at about 116 m. aMSL (or 380ft aMSL), assuming the water is at MSL. architecturalprints.com.au/shop/posters-prints/... 3. He was facing about 20 to 25 degrees N of W (i.e., about WNW). (Determined by protractor on Google map from center of span to Blues Point tower.) www.myplace.edu.au/TLF_resources/R3352/description.html Collier Smith |
