← HistoryWhich mechanism allowed early suspension bridges to span longer distances than arch bridges?
A)Cables distributing tension forces✓
B)Piers resisting compressive forces
C)Decks absorbing vibrational forces
D)Foundations anchoring shear forces
💡 Explanation
When load is applied, cables distribute tensile forces to anchor points because suspension concentrates tension, unlike compression in arches. Therefore cables handling tension allow for longer spans, rather than piers handling compression, decks absorbing vibration, or foundations handling shear which are less critical for span length.
