Question

Derive gauge factor expression.​

Answer 1

Answer :

Let's start the answer

Explaination :

The Strain Gauge Factor Derivation is an example of a passive transducer that uses the variation in electrical resistance in wires to sense the strain produced by a force on the wires.

Since strain can be measured more easily by using variable resistance transducers, it is a common practice to measure strain instead of stress, to serve as an index of pressure.

If a metal conductor is stretched or compressed, its resistance changes on account of the fact that both the length and diameter of the conductor changes

The following types of Strain Gauge Factor Derivation are the most important.

• Wire Strain Gauge
• Foil Strain Gauge
• Semiconductor Strain Gauge
