Challenge Problems
Push your limits with advanced challenges
A strain gauge on a structural element reads a voltage of 2V under no load, increasing to 3V under load. Calculate the strain if the gauge sensitivity is 1V/μstrain.
💡 Hint: Use the sensitivity to deduce how voltage change translates to strain.
An accelerometer on a bridge detects a consistent frequency in vibrations of 10 Hz. If the amplitude changes, how might this indicate structural health?
💡 Hint: Consider how amplitude relates to the health and stability of structures.
