Question

Identify the material used to construct the bridge shown below: 

• A. Steel
• B. Hard Wood
• C. Concrete
• D. Cast Iron

Hint:

Steel is preferred in construction for its durability and load-bearing capacity.

Answer 1

The Correct Option is A

Steel is used for constructing the bridge due to its high strength and rigidity, making it ideal for such structures.
Its excellent tensile strength allows it to withstand heavy loads and resist deformation under stress, ensuring the stability and safety of the bridge.
Additionally, steel is durable and can endure various environmental conditions, including temperature changes and corrosion when properly treated.
Its versatility also allows for easier fabrication and assembly, enabling the construction of long spans and complex designs.
These properties make steel the preferred material in modern bridge engineering.
