⚖️ Does the design's weight matter a lot?Weight-critical use case?📐 Compare specific strength = strength ÷ densityPick material with highest specific strength that meets the load🚀 Lighter part: better fuel economy, range, speed🏗️ Compare absolute strength & cost insteadHeavier material is fine — the ground carries the load for freeYes: aircraft, car, bikeNo: static structure, e.g. building foundation
