Engineering Worksheet: Earthquake-Safe Buildings

Engineering lesson 21: Earthquake-safe buildings · Set 815 · 40 questions

Engineer's tip (Low, wide, flexible): Safer: wide base, flexible joints, bracing, steel in concrete, light roof, rubber pads, simple shape. Less safe: heavy tops, narrow bases, loose bricks, no steel, brittle joints. Tipping: compare height ÷ base width — the smaller it is, the steadier the block.
