Which of the following bridge is used for the movement of trains?
- ABeam Bridge
- BTruss BridgeCorrect
- CSuspension Bridge
- DNone of these
Solution
Concept
Railway Truss Bridges
Formula
No formula applicable
Step-by-step solution
1. Identify the requirements for railway bridges, which need high strength, rigidity, and heavy load-bearing capacity to support moving trains. 2. Recall that truss bridges use interconnected triangular frameworks to efficiently distribute heavy dynamic loads. 3. Match this characteristic to Option B (Truss Bridge).
Explanation
Truss bridges use connected triangular structures to provide exceptional strength, high load-bearing capacity, and rigidity. This enables them to safely handle the heavy weight and dynamic forces of moving trains.
Shortcut
Remember 'T' for Train = 'T' for Truss Bridge (Trains need Trusty Trusses to carry heavy loads).
Common mistake
A common mistake is selecting suspension bridges because of their visibility in long-span highway designs, overlooking that they are generally too flexible to support the heavy, concentrated dynamic loads of trains compared to rigid truss bridges.
Correct answer: B) Truss Bridge
