document.write( "The phrase \"wipes the windshield over a distance of 14 inches\" is at best irrelevant and at worst contradictory.  Presumably it would mean the tip of the wiper blade travels 14 inches; but with a radius of 25 inches and an angle of 125 degrees, it travels far more than that. </SPAN>\n" );
