Read the assertion and reason carefully to mark the correct option out of the options given below:
Assertion : The bridges declared unsafe after a long use.
Reason : Elastic strength of bridges losses with time.
  • a)
    If both assertion and reason are true and the reason is the correct explanation of the assertion.
  • b)
    If both assertion and reason are true but reason is not the correct explanation of the assertion.
  • c)
    If assertion is true but reason is false.
  • d)
    If the assertion and reason both are false.
Correct answer is option 'A'. Can you explain this answer?

A bridge during its use undergoes alternating strains for a large number of times each day, depending upon the movement of vehicles on it when a bridge is used for long time, it losses its elastic strength. Due to which the amount of strain in the bridge for a given stress will become large and ultimately, the bridge may collapse. This may not happen, if the bridges are declared unsafe after long use.

Understanding the Assertion and Reason
The assertion states that bridges are often declared unsafe after prolonged use. This is a common scenario in civil engineering where structures undergo wear and tear over time.
Key Points of the Assertion:
- Long-term Use: Bridges are subjected to constant loads and environmental factors.
- Safety Concerns: Regular assessments are necessary to determine the structural integrity of bridges.
Analyzing the Reason
The reason provided is that the elastic strength of bridges diminishes over time. This relates to the material properties of the bridge components, which can degrade due to various factors such as fatigue, corrosion, and environmental impact.
Key Points of the Reason:
- Elastic Strength: Refers to the ability of a material to deform elastically (i.e., return to its original shape) when a load is applied.
- Time Factor: Over time, materials can lose their elastic properties due to repeated stress and environmental exposure.
Connecting Assertion and Reason
Both the assertion and reason are true. Bridges can indeed become unsafe after many years of service due to the loss of elastic strength. The reason directly explains why bridges may be declared unsafe; as the elastic strength diminishes, the ability to safely carry loads decreases, leading to safety concerns.
Conclusion
Given that both statements are true and the reason adequately explains the assertion, the correct answer is option 'A': Both assertion and reason are true, and the reason is the correct explanation of the assertion.
