Conclusion
Repairing the tower became more than restoration. It turned into a classroom where alloys were stories and welding seams were stitches that healed a city’s past to its present. They replaced the cracked pinion with one built from a high-tensile steel whose microstructure Meera had chosen after reading about grain refinement. Arun showed her how to inspect a fillet for stress concentration; Meera showed him how to simulate the load in software and estimate fatigue life.
