how a sail works, who can help me explain?
"Simple Simon" wrote in message
The convex side of the sail or the leeward side directs the air over a longer path. This longer path for the air lowers the pressure because said air must move faster to cover the increased cord. Shouldn't that be "chord"? Yea man! The chord is a straight line, not the curved part that the air moves faster over. -- Wally I demand rigidly-defined areas of uncertainty! www.art-gallery.myby.co.uk |
