Suspension Bridge Cable Mechanics
Estimated Time: 2–3 min quiz | PDH/CPD: 0.75 hr (incl. review & study) | Difficulty: Advanced
Question: In a suspension bridge, why does a concentrated heavy load (like a truck convoy) typically cause greater local deflection than the same total weight distributed uniformly?
- Concentrated loads create lower cable tensions
- Point loads force sharp cable geometry changes while distributed loads follow smooth curves
- Hangers cannot effectively transfer concentrated loads
- Distributed loads benefit from dynamic amplification
