ed along whichthe normal stresses have their maximal values. If these stressesare tensions which are greater than the elastic limit of the material,then the material will rupture along this curve (maximal tensioncurve). In a similar way a curve may be drawn through thepoint along which the normal… … MAP OF THE ARAPAHOE GLACIER AUGUST 1902 i v*MILE 1 A Fig. 102.
