Supersonic Lift? Lift appears to be from the angle of attack, due to the deflection of flow-stream in supersonic flight but then in subsonic flight the pressure difference causes lift. So what is going on here that i am missing? Why such a change? Its starting to confuse me.

Im having some trouble understanding how lift is generated at supersonic speed as apposed to subsonic speed. Viscous effects at high speed are greatly reduced and a normal airfoil from subsonic flight is not suitable for such applications. I have had a good read on wiki and other sites but i...

Im starting to give up on this one, every time i try to figure it out i get an answer that is miles off. Im looking to find ZL, can someone show me how this is done? I think my problem is with the dependent voltage. http://img31.imageshack.us/i/unledak.png/

kmarnas86 you thinking out of that square arnt you, that didnt even cross my mind, well done scott1 even if he could do that the bridge would still have 3 kg more weight on it and it would be the same as the guy holding them, therefore break bridge

This one may take a while to get to the physics but is a good challenge for a mate with a sharp mind. My friends would like to know the answer and the physics behind it, so any answers would be appreciated. There was an OLD man out for a walk one afternoon and he decided to walk across a long...
