Question

Can the normal strain on the free surface of a body be measured in a
particular direction using an electrical resistance strain gage? Give an example?

Expert Solution

Step 1

The magnitude of the strain measures using the device strain gauge. Strain gauge works on a different principle. The electrical resistance strain gauge work based on the change in resistance on the strain gauge due to the application of force or any other external factors on the material.
