Strain gage and Extensometer both are same purpose to check the stress and strain in selective test pieces, but traditional they were using strain gage its take the preparation time is high and Extensometer we are check the directly both results are same.
I think torsional strain happens only when two groups are eclipsed in relation to their positions to each other. This strain can be relieved by rotation about the carbon carbon bond. But steric strain can happen all the time. (when two groups are eclipsed, gauge or staggered in relation to each other.)
The difference between screw gauge and spherometer is that spherometer can measure the dimensions of spherical surfaces but screw gauge cannot
A pressure gauge measures blow, a vacuum gauges measures suck
A triple beam balance uses a set of three beams to determine Weight.A digital balance uses (generally) a strain gauge system to determine the Mass of a substance.
transmitter means to carry towards signal or panel & gauge means to indicate at on spot by clock.

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.
How I know if the strain gauge is gone
A standard specimen is loaded on a tensile test machine; load,P, is applied and measured with a load cell and strain, e, is measured with a strain gauge extensometer. In the linear region, load is divided by specimen area to get stress, s, and the modulus, E, is determined from Hooke's law, where E = s/e

Advantages and disadvantages of strain gauge
"Mechanical Strain gauges" do not have inductance. There are many types of strain gauge: Mechanical, photoelastic, electrical etc.... Are you wanting the inductance of an electrical strain gauge? if so which type?
20 gauge is larger
The difference between screw gauge and spherometer is that spherometer can measure the dimensions of spherical surfaces but screw gauge cannot
it is more sensitive small gauge size low hysteresis
The size of the bore.
Load cells are strain gauge based sensors used for weighing applications.
