6.1.2. Based on Working Principle

Try these first

1. 1.

   What are mechanical sensors used for in civil engineering?

   Hint

   Think about structural integrity.

2. 2.

   Give an example of an electrical sensor.

   Hint

   Consider sensors that measure resistance.

3. 3.

   What principle do mechanical sensors rely on?

   • Sound Waves
   • Physical Changes
   • Electromagnetic Fields

   Hint

   Consider their function in stress measurement.

4. 4.

   True or False: Electrical sensors can measure resistance changes.

   • True
   • False

   Hint

   Focus on their basic operational principle.

5. 5.

   Design a basic monitoring system that incorporates mechanical and ultrasonic sensors for a bridge. Describe the data the system would collect.

   Hint

   Think about how each type's data integrates to improve safety.

6. 6.

   Critically assess a hypothetical failure in an electrical sensor during extreme temperatures. What measures could be taken to avoid such failures?

   Hint

   Consider environmental impacts and sensor redesign strategies.
