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.
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.
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.
