@natt_math: Why engineers love the Pratt Truss vs. Howe Truss The Howe Truss (top) forces its longest diagonals into RED compression, creating a dangerous risk of structural buckling. The Pratt Truss (bottom) flips the diagonals, keeping those long beams in safe, stable BLUE tension. #truss #engineering #statics #structuralengineering #bridgeengineering
