A question for the math, engineering, and geometry folks out there. A constant cross section beam, end supported and center loaded, describes a curve. What curve? I suspect it's catenary, but I haven't found anything anywhere giving even a clue one way or another. If no one out there can produce a reference, I'll resort to attempting to work out the math describing the catenary and comparing deflection rates at various points along the beam with available formulae. But math is hard on me, and I'd appreciate any specifics anyone out there may have that would help minimize the inevitable frustration. Thanks, just in case... Ron N
