The placement of the strain gages on the four sides of the tension member provides a load cell which is essential independent of either bending or torsional loads. When a bending moment M is applied to the tension member either by a transverse load or by an eccentrically applied axial load. The moment M may have any direction relative to the axes of symmetry of the cross section. The components of the moment ? 1 and ? 2 will produce resistance changes in the gages as follows: For M1 ∆?

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
