Volumetric strain of a deformed body is defined as the ratio of the change in volume of the body to the deformation to its original volume. If V is the original volum and dV the change in volume occurred due to the deformation, the volumetric strain ev induced is given by ev =dV/V
Consider a uniform rectangular bar of length l, breadth b and depth d as shown in figure. Its volume V is given by,
This means that volumetric strain of a deformed body is the sum of the linear strains in three mutually perpendicular directions.

What is molarity ..volumetric analysis?
volumetric analysis is the means of estimating quantities of substances
How would you stir a solution freshly prepared in a volumetric flask?
You swirl the liquids in volumetric flasks to mix them.
How does the temperature and density play a role in calibration of glassware?
Glassware for volumetric measurements (pipettes, burettes, volumetric flasks etc.) are calibrated at 20 oC.
What is Absolute error of volumetric flask?
The accuracy depends on the volume of the flask; this accuracy is standardized in standards as ASTM, CEN, GOST, etc. For important works class A volumetric flasks, pipettes and burettes are recommended. As an example see the list below.
What are the the four classifications of volumetric process?
Another name for volumetric processes is titration. Four different kinds of these processes are acid or base, redux, complexometric, and precipitation.
