The feasibility of graphical stress analyzing methods in photoelasticity based on the equation of equilibrium in polar coordinates: “the wedge method” and “the arc method” is examined by the experiment of a circular ring subjected to a diametral compression. The results obtained show that the former enables us to determine the stress components separately along a straight line more accurately than the usual methods, while the latter to analyze stresses along a circular arc satisfactorily.
