Engineer’s design dilemma

It’s been almost a week of work at the workshop and the metal structures are finally taking shape. Along the way, I had spent many hours consulting with experienced mechanical engineers on whether the structure would hold the weight I wanted them to. It was mind-boggling the amount of data they had on their finger-tips. In addition to this, I spent countless hours drawing-up CAD models, performing FEM analysis and filling-up my notebook with stress calculations. Do I trust the theoretical calculations on paper or the empirical advice of an experienced engineer? Would they add-up in the end?

This is a problem most of the engineers face. Its cheap to buy a notebook, pen, a book and workout an engineering problem from a college dorm or an office or a home. What’s not cheap is building the full-sized contraption in a humid, dusty workshop and then testing if your assumptions were correct. Would India ease this transition from chalk-board to machine-shop for budding inventors? 

But the joy of working-out complex models on paper is incredible. Dr. Amar Bose had worked out the theory behind ‘noise-cancelling headphones’ on a flight between 2 cities. ‘Wearable device’ nevertheless, but extremely complex mathematics behind the electronics. I guess it did add-up in the end for Bose corp.
