17.2.1. Sensors

Try these first

1. 1.

   What do strain gauges measure?

   Hint

   Think about what happens when you put pressure on an object.

2. 2.

   How do accelerometers work?

   Hint

   Consider how your phone detects movement.

3. 3.

   What do strain gauges primarily measure?

   • Temperature
   • Deformation
   • Vibration

   Hint

   Think about how forces affect the shape of a material.

4. 4.

   True or False: Accelerometers can only be used in transportation vehicles.

   • True
   • False

   Hint

   Consider other applications outside of vehicles.

5. 5.

   A new bridge is being constructed. Explain how you would integrate different sensors for SHM and their respective roles.

   Hint

   Consider the environment and how different forces act upon the structure.

6. 6.

   Discuss the implications of fiber-optic sensors compared to traditional sensors in environments with electromagnetic interference.

   Hint

   Think about where electrical interference might be encountered in civil engineering.
