principals | R Documentation |
Strainmeters are generally designed to resemble common strain-gauge rosette configurations to simplify gauge combinations.

## Default S3 method:

If there are only two components of the LSM the angle of maximum shear cannot be solved for.
The calculation is based on 2-D Mohr's circle with the 1-axis being normal and the 2-axis being shear.
