When the wind doubles does the pressure in the sails increase 8 times?
When the apparent wind speed is doubled, the pressure on the sail is quadrupled. That is because the pressure on the sail (or the side of your house or a billboard sign) is proportional to the square of the speed of the wind. If the wind speed triples, then the pressure goes up by a factor of nine, because three squared is nine.

Lyrics to Tuesdays Gone by Lynard Skynard?
Train, roll on, on down the line. Won't you, please, take me far away. Now I feel the wind blow outside my door. Means I'm, I'm leaving my woman at home. Tuesday's gone with the wind. Oh, my baby's gone with the wind. And I just don't know, oh, where I'm going. I just want to be left alone. Well, when this train ends I'll try again oh, but I'm leaving my woman at home. Tuesday's gone with the wind. Tuesday's gone with the wind. Tuesday's gone with the wind. My baby's gone with the wind. Train, roll on, Tuesday's gone. Train, roll on many miles from my home. See I'm, I'm riding my blues away, yeh. Tuesday, you see, she had to be free. Lord, but somehow I've got to carry on. Tuesday's gone with the wind. Tuesday's gone with the wind. Tuesday's gone with the wind. My baby's gone with the wind. Train, roll on 'cause my baby's gone.. I'm riding my blues away, baby turn around my blues ride on, train, ride on, train ridin' my blues, babe come back to me, babe come back to me oo-oo-oo-oo-oo-ooh train..
