Four active gages with pairs subjected to equal and
opposite strains (beam in bending or shaft in torsion).
Units for load and dimensions
must coincide with those for elastic modulus.
Load (lbf, etc.),
Elastic Modulus (lbf/in 2 , etc.),
Distance from Load (in, etc.),
Width (in, etc.),
Thickness (in, etc.),
Gage Factor (nondimensional),
