Most of the times when we are called in an operating plant having vibration, we do not have luxury of hiding our inaccuracies of prediction of fatigue life with ample factor of safety. Plant needs shutdown or can wait for next shutdown .. we need to choose among the two. If we prove wrong, faith of people on us will be lost forever!

I do not want our youth to obey us; replace us not by just age count, but by replacing us with improved service to the customers through deep work of real value, creativity and productivity.
New India of our young enginners must be safe, cost effective in life cycle cost and environmental foot print! If 5G days become more unsafe than radio days of yester years, there must be somewhere something wrong in our development model. Youth in China or Germany can be responsible, why can't our own learn from them.
