Why We Build Structures to Fail at 300%: Factor of Safety

Summary: Most people think engineers “overbuild” things because they’re wasteful or overly cautious. In reality, extra strength is built in on purpose, to deal with uncertainty, hidden flaws, and the fact that real life never follows the math perfectly. This video explains why designing for the worst case is often the smartest and safest engineering decision. In this video, we break down: Why engineers avoid designing things to be “just strong enough” and what can go wrong when there’s no margin for error What safety factors are and how engineers use them to protect against uncertainty, misuse, and unpredictable conditions Examples like elevator cables, airplane wings, bridges, and everyday objects that rely on overbuilding to stay safe The biggest misconception about efficiency, and why systems that look “overengineered” are often more reliable, forgiving, and resilient over time Chapters: 0:00 – Intro 0:41 – The “Just enough” idea 1:12 – Engineering includes assumptions 2:08 – Why safety factors exist 3:56 – Simple example 4:57 – Materials are not perfect forever 6:20 – Time is a load too 7:20 – When “efficient” becomes fragile More Like This: Videos: Gas vs Diesel: How An Internal Combustion Engine Works:    • Controlled Explosions: How Internal Combus...   Shorts: Your car runs on explosions:    • Your Car Runs on Explosions   Gasoline vs Diesel simplified:    • Gasoline vs Diesel simplified   Fire on a Schedule:    • Fire on a schedule   About This Channel: This channel explains engineering and STEM ideas using simple animations and calm narration, designed for curious people.
