.] The points E and L in vm, vertically over Er andL in vm!, are now fixed; they are the intersections of thespecial polygon required, with vm. The ordinates between vmf and the trial equilibriumpolygon have been called z instead of z\ they are pro-portional to the respective 2s of the required… … Z\{yz) = l\(yz>) .
