![]() "Peter Dohm" wrote in message news ![]() "Capt. Geoffrey Thorpe" The Sea Hawk at wow way d0t com wrote in message ... http://www.fi.edu/wright/again/wings...r/golf-01.html description and a drawing... ... So all of the articles agree on a couple of points, and appear to have obtained the same photo for publication. However the Magnus Effect, while well known to be true to every golfer (usually in a detrimental way) appears to be backward in some sense. For the moment, this appears to have moved from my Solved Problems List to my Unsolved Problems List. Peter Dunno, looked OK to me. If the ball is flying across your screen from right to left think of an airfoil moving from right to left, low pressure on top, circulation has to be clockwise in this view to accelrate the flow across the top and decelerate it around the bottom - "1877, British scientist P.G. Tait learned that a ball, driven with a spin about a horizontal axis with the top of the ball coming toward the golfer produces a lifting force. This type of spin is know as a backspin." That would be clockwise in a view where the ball is moving from right to left... Note: Have you ever seen a drawing or wind tunnel picture where the object was traveling from left to right or the air was moving from right to left? How did we become so consistant? -- Geoff The Sea Hawk at Wow Way d0t Com remove spaces and make the obvious substitutions to reply by mail When immigration is outlawed, only outlaws will immigrate. |
