Problem $7(4$ points$)$: Figure $3$ shows a bridge circuit with one axial gauge and one Poisson gauge subject to a bending, as in the prior problem. Assume the same circuit as in the prior problem, except for the orientation and location of the gage at $R_3.$ While the figure doesn't make it clear, assume both gages experience the same bending moment, $M=FL.$

b$.$ Proceed as in part $($c$)$ of the prior problem

Figure $3.$ Half$-$bridge circuit $($left$).R_3$ and $R_4$ measure transverse and axial strain the beam $($right; gage size exaggerated; true positions have centers experiencing equal bending moment$).$
