1. 1.

   What is the role of tension in bridge cables?

   Hint

   Think about how tight cables are in bridges.

2. 2.

   How can tall buildings be modeled during seismic analysis?

   Hint

   Consider how a beam behaves under a load.

3. 3.

   What is the primary factor influencing the wave speed of bridge cables?

   • Material type
   • Temperature
   • Tension

   Hint

   Consider the relationship between tension and wave propagation.

4. 4.

   True or False: Resonance can enhance structural performance.

   • True
   • False

   Hint

   Think about the negative effects of resonance.

5. 5.

   Analyze how a significant change in cable tension might affect the wind load resistance of a bridge.

   Hint

   Consider how different tension levels change the dynamic response.

6. 6.

   Evaluate the vibrational impact of a train passing on railway tracks modeled as semi-infinite strings along an elastic foundation.

   Hint

   Think about how vibration frequencies relate to comfort and structural safety.
