Round Thick Diameter Specimens
A typical gaged specimen has three levels of strain gages. The gages allow you to
determine bending strains at each level. Analysis of the strain readings produce a
profile of the grip alignment.
Gage placement
Use twelve gages on large diameter round specimens. Attach and number them
as shown here.
