Engineering laws part 1

Sad but true

Law #1: In any calculation, any error which can creep in will do so.

Law #2: Any error in any calculation will be in the direction of most harm.

Law #3: In any formula, constants (especially those obtained from engineering handbooks) are to be treated as variables.

Law #4: The best approximation of service conditions in the laboratory will not begin to meet those conditions encountered in actual service.
