Does a convex lens invert images?
Yes. Image formed by convex lens is laterally inverted. However, It should be kept in mind that convex lens can form both real and virtual images. If the object is placed beyond F (Focus), then real image will be formed and laterally inverted. However, if the object is placed between F and C. Then the images formed will be virtual but NOT laterally inverted. For concave lens, all images formed is on the same side so the images formed is NOT laterally inverted
Why can't helicopters fly upside down?
Actually, a helicopter can fly upside down but not for long.If you go to... http://www.guardian.co.UK/notesandqueries/query/0,,-186989,00.htmlYou can get answer to why I say they can fly upside down. They can only fly upside down for a certain amount of time though.My reference is ^. I am NOT playgerizing.The reason is due to the design of the rotor blades and the grips that hold them and the mast. It is how the parts were designed to carry loads. Most Mast and Blade designs are build to carry a load UNDER it but it is not rigid enough to invert it so the load is above it.Most vintage Bell Helicotpers had teetering rotors and was limited to about 60 degree banks because the rotor blade would bang against the mast. In the 1980's they had some accidents involving "mast bumping" and they had to redesign the rotor system to include bumper pads or stiff springs to absorb the shock of the blade hitting the mast.However, most times that helicopters are flown upside-down they are flying such that the G-forces is still loading the rotor blades in the same direction. They can do a Loop or a Split-S and the momemtum of the helicopter keeps the rotor blades loaded in a positive force. They very seldom fly inverted in level flight so the load on the rotor is Negative.
