Ferrous ammonium suifate, Mohr s salt, FeS04 (NH4)2S04 6H2O—0.5N 196 g per liter. Ferrous sulfate, FeS04 7H2O—0.5N 80 g per liter add a few drops of H2SO4. 

A mixture containing only KCl and NaBr is analyzed by the Mohr method. A 0.3172-g sample is dissolved in 50 mL of water and titrated to the Ag2Cr04 end point, requiring 36.85 mL of 0.1120 M AgNOa. A blank titration requires 0.71 mL of titrant to reach the same end point. Report the %w/w KCl and NaBr in the sample.

Powder Mechanics Measurements As opposed to fluids, powders may withstand applied shear stress similar to a bulk solid due to interparticle friction. As the applied shear stress is increased, the powder will reach a maximum sustainable shear stress T, at which point it yields or flows. This limit of shear stress T increases with increasing applied normal load O, with the functional relationship being referred to as a yield locus. A well-known example is the Mohr-Coulomb yield locus, or... 

Materials sueh as east-brittle metals and eomposites do not exhibit these uniform properties and require more eomplex failure theories. Where the properties Su. and Su of a brittle material vary greatly (approximately 4 1 ratio), the Modified Mohr Theory is preferred and is good predietor of failure under statie loading eonditions (Norton, 1996 Shigley and Misehke, 1989). 

The stress, L, determined using the Modified Mohr method effeetively aeeounts for all the applied stresses and allows a direet eomparison to a materials strength property to be made (Norton, 1996), as was established for the Distortion Energy Theory for duetile materials. The set of expressions to determine the effeetive or maximum stress are shown below and involve all three prineipal stresses (Dowling, 1993) ...
