    "Airey Points" for a rectangular plane

    I know the airey points for a beam (two support points that produce the minimum deflection from a straight line), but I cannot find a formula for an equivalent for 3-point support of a flat rectangular plane.

    supercharged vs normally asperated engines

    If the compression ratio(CR) of an engine is set as high as is reasonable for the fuel used, how can a supercharger (or turbosupercharger) not cause detonation when it increase the incoming charges pressure? Or, to ask the question another way, isn't supercharging the same as increasing the CR.

    Connecting rod shape

    I cannot find any analysis of a I-shaped connecting rod vs. a H-shaped. The H-shaped rods seemed to be used in the more expensive applications, but I cannot figure out why it should be preferable.
