strain gage

Thân thiện

A technician attaches a strain gage to a metal beam.

Definition

Noun: A device designed to measure the amount of deformation (strain) in an object's surface when a force is applied. It typically works by converting mechanical strain into a change in electrical resistance.

Usage

A "strain gage" is used in engineering and materials testing to analyze stress, monitor structural integrity, and measure force, torque, or pressure. It is attached directly to the surface of the object being tested.

Examples

• Noun:
  • The engineer attached a strain gage to the bridge's support beam to monitor for any excessive flexing.
  • Accurate measurement from the strain gage confirmed the material was within its safe stress limits.

Advanced Usage

• "to install/apply a strain gage": The process of bonding the device to a surface.
  • The technician carefully applied the strain gage to the aircraft's wing.
• "strain gage reading": The data output from the device.
  • The strain gage reading indicated a small but significant deformation.

Variants and Related Words

• Strain gauge: An alternative, more common spelling for the same device.
• Load cell: A transducer that often uses internal strain gages to measure force or weight.
• Extensometer: Another instrument for measuring deformation, often used for larger strains.

Synonyms

• Strain sensor
• Deformation gauge

Related Phrases

• Strain gage rosette: A cluster of multiple strain gages arranged in a specific pattern to measure strain in different directions.
  • A strain gage rosette was used to determine the complex stress state at the joint.
• Strain gage factor: A numerical value representing the sensitivity of the gage.
  • Selecting a strain gage with the correct gage factor is critical for the experiment.
