@amazeifystore: Rubber shouldn’t act like glass, but the cold changed everything. ❄️ The Challenger O-ring failure remains one of the most significant engineering lessons in history. When those secondary seals lost their elasticity, they couldn't spring back to fill the gap, leading to a catastrophic chain of events. It is a haunting reminder of how material properties can shift in extreme conditions. How do you account for variables you can’t control in your projects? 👇 Follow for more engineering case files. #engineering #challenger #nasa #stem #physics #failureanalysis #materialscience #space #History #engineeringlife #Tech
