What is a strain gauge used for and how does it work in measuring mechanical strain?
A strain gauge is a device used to measure mechanical strain, which is the deformation of an object under stress. It works by changing its electrical resistance in response to the strain applied to the object it is attached to. This change in resistance is then converted into a measurable electrical signal that can be used to determine the amount of strain the object is experiencing.

What are the uses of strain gauges in measuring mechanical deformation?
Strain gauges are used to measure mechanical deformation in various applications such as structural testing, material testing, and stress analysis. They are commonly used in industries like aerospace, automotive, and civil engineering to monitor the strain and stress levels in structures and components. By detecting changes in resistance caused by deformation, strain gauges provide valuable data for evaluating the performance and safety of materials and structures.
What tool is used for measuring air pressure?
A barometer is the tool used for measuring air pressure. It can be either an aneroid or mercury barometer.
What is the relationship between stress and strain in materials under mechanical deformation?
The relationship between stress and strain in materials under mechanical deformation is described by Hooke's Law, which states that stress is directly proportional to strain. This means that as a material is subjected to a force (stress), it will deform (strain) in a predictable and linear manner. The relationship between stress and strain helps engineers and scientists understand how materials behave under different conditions and can be used to predict their mechanical properties.
What is the difference between instrument and gauge?
An instrument is a device used for measuring or monitoring a particular quantity or level, while a gauge specifically refers to a device used for measuring pressure or depth. In general, an instrument has a broader application, encompassing various types of measurement devices, while a gauge is more specialized in its use.
What is the stress-strain relationship formula used to calculate the mechanical behavior of a material under loading conditions?
The stress-strain relationship formula used to calculate the mechanical behavior of a material under loading conditions is typically represented by the equation: Stress Young's Modulus x Strain. This formula helps to understand how a material deforms and responds to applied forces.

What is strain gauge extensometer?
A strain gauge extensometer is a device used to measure the deformation (strain) of an object under stress. It consists of a strain gauge, which is a sensor that detects changes in resistance due to deformation, and a mechanical structure that ensures accurate placement on the test specimen. Extensometers are commonly used in materials testing to monitor how materials respond to applied forces, providing critical data for engineering and research applications. Their precise measurements help in assessing material properties and structural integrity.

Difference between unbonded strain gauge and bonded strain gauge?
The essential difference is that the bonded strain gauges are bonded on to the specimen whose strain is being measured whereas the unbonded strain gauges are not bonded on to the specimen. As the bonded strain gauges are well bonded on to the specimen, the entire strain being experienced by the specimen is transferred to the strain gauge. However, the bonded strain gauges are affected by temperature changes and also due to transverse strains.For transverse strains and ambient temperature compensations, suitable circuits for compensation can be used using Wheatstone's bridge. The unbonded strain gauges cannot transfer the strain of the specimen to the strain gauge and hence it is used mainly for displacement, or pressure or force transducers. It is least affected by transverse strain and temperature compensation of unbonded gauges cis automatically eliminated using Wheatstone's bridge.
