#54507, "RE: Titanic deck supports"
In response to In response to 11


          

Just came across a calculation for camber in CC Pounder's book, pg85. He says it is a flat parabola giving y=a(1-B^2/L^2) where y is the height at distance B from midships. L is half the breadth of the deck and "a" is the camber height at midships.

I ran it on a spreadsheet and found that for the Titanic's 3 inch rise over 92 foot breadth, the difference compared to a radius was never more than 0.00002 inches. Not worth using the parabola over a simple radius. The advantage to H&W may have just been that they wouldn't have to manually calculate the radius first.
