Research on Strain Gage and Data Acquisition Device

What is a strain gage?

A. A device that measures temperature

B. An electrical transducer that changes electrical resistance values based on mechanical deformation

C. A sensor that detects light intensity

D. A tool for measuring air pressure

Answer:

B. An electrical transducer that changes electrical resistance values based on mechanical deformation

A strain gage is an electrical transducer used for measuring mechanical quantities. It changes its electrical resistance values in response to the mechanical deformation it undergoes. This allows it to accurately capture and translate mechanical changes into electrical signals.

Strain gages are commonly used in various industries and applications where monitoring strain and deformation is essential, such as structural engineering, material testing, and biomechanics.

By understanding the principles of strain gages, engineers and researchers can gather valuable data to analyze and improve the performance and durability of materials and structures.
