In the context of Infrastructure 4.0, the Internet of Things (IoT) is applied to bridges primarily for
- AReal-time structural health monitoring through sensors that detect strain, vibration and tilt.Correct
- BProviding free Wi-Fi to the drivers.
- CIncreasing the height of the bridge automatically during floods.
- DChanging the colour of the bridge based on the weather.
Solution
Concept
Internet of Things (IoT) in Structural Health Monitoring
Formula
N/A
Step-by-step solution
1. Analyze the application of IoT in bridge infrastructure. 2. Recognize that IoT sensors continuously track structural health by detecting strain, vibration, and tilt in real time. 3. Select Option (a) as the correct answer.
Explanation
Option A is correct because IoT sensors installed on bridges continuously track structural health by detecting movements, vibrations, and stress in real time. This helps detect potential damage early and ensures safety.
Shortcut
To remember the primary role of IoT in infrastructure, use the rule "IoT = Sense & Monitor": - Sense & Monitor: IoT acts as the bridge's "nervous system," constantly tracking structural health (strain, vibration, tilt) in real time. - Safety First: Industrial IoT focuses on early damage detection and structural safety, not consumer features (like Wi-Fi) or physical modifications.
Common mistake
A common mistake is selecting options B or D by confusing consumer IoT applications (like Wi-Fi or aesthetic features) with industrial infrastructure IoT, which focuses on safety and monitoring. Another mistake is choosing option C by overestimating IoT capability, confusing data sensing and monitoring with automated mechanical lifting systems.
Correct answer: A) Real-time structural health monitoring through sensors that detect strain, vibration and tilt.
