POSITIONING STRAIN GAGES TO MONITOR BENDING,
AXIAL, SHEAR, AND TORSIONAL LOADS
In the glossary to the Pressure
Reference Section, strain is defined
as the ratio of the change in length to
the initial unstressed reference
length. A strain gage is the eleme
Structural Axial, Shear
and Bending Moments
Recall from mechanics of materials that the internal forces P
(generic axial), V (shear) and M
(moment) represent resultants of
the stress distribution acting on
the cross section of the beam.
