- Strain is defined as the configuration change relative to the initial configuration.
Strain = Change in dimension/ Original dimension = x/L
- Being the ratio of two similar values, strain has neither units nor dimensions. It lacks dimension.
- Its dimension can be expressed as M0L0T0
Strains are of three types
Longitudinal strain - It is the ratio of change in length to the original length.
Longitudinal strain = Δ l /l
Shearing strain - It is the ratio of change in angle to which it is turned to its distance from the fixed layer.
Shearing strain = Δ l /l
Volumetric strain - It is the ratio of change in volume to the original volume.
Volumetric strain = Δv/v
What is the Dimensional Formula of Strain? M0L0T0, M1L-1T-2, M0L0T-1, None of the above
M0L0T0 is the dimensional formula of strain. It is the ratio of change in dimension to original dimension.
