Which tent pole material offers the best balance of strength, flexibility, and lightweight performance for high-altitude trekking?
उत्तर Answer: ग
Aluminum (typically 7000-series) — bends rather than snaps, strong and light; fiberglass is heavy/brittle, steel is heavy, wood is obsolete
Backpacking gear references rate aluminum poles as the best strength/flexibility/weight balance; fiberglass heavier and cracks, steel too heavy.
