Stress is the force exerted on the jet wing. Strain is bending to the elasticity limit; if it bends beyond that, it breaks.
My dad was the test engineer who discovered, with a torque rod, that the outside two wing cylinders would break on the F-104. But his superior thought faulty testing side load was to blame. So Lockheed skipped the redesign.
When the prototype flew, the same cylinders were compressed. The redesign, so late in the game, was much costlier.
We all have our breaking points, when too much stress is straining our hearts more than we can bear. Just like different materials and different designs have different load capacities, so too all of us have different limits. There’s no point in making fun of me if my capacity to enduring stress is lesser than yours.
I want to spring back into the original shape. I don’t want to be distorted by the strain of bitterness, disillusion, betrayal. God increase my elasticity!
