POSITIONING STRAIN GAGES TO MONITOR BENDING,
AXIAL, SHEAR, AND TORSIONAL LOADS

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.
