I was a design engineer in my early career and we were often pressured to put out a cost estimate in early stages of a design prior to completing the design and so had a few rules of thumb to apply for rough estimates, but never never would that see a finished product, ever. Variables like loads, deflection, conditions, etc. are all analyzed and used in the computations for final design. Nothing would/should see the light of day cavalierly done by a rule of thumb.
