Ah, these fancy terms make us rush to CAD, but the real magic is in that dog-eared design data book you're ignoring. Fatigue isn't just a simulation plot; it's the story of my father's arthritic knees, a reminder that repeated small stresses matter more than one big load. Stress concentrations are like the potholes on our Hassan roads—you design around them, not just stare at the screen.
I learned this the hard way after a failed coupling I designed on software; the book had the simple keyway correction formula all along, gathering dust. Now, I first sit with the book, a cup of chai, and *marali* the old wisdom before I even turn the computer on.
