  Angle of Repose by Wallace Stegner | Book Club Discussion ...

  The geologic term 'angle of repose', defines the angle of the slope at which debris will cease rolling downhill and settle in one place, as in a landslide. Why do you think Stegner chose this term for the title of his novel? By the end of the novel, has Lyman reached his own angle of repose?

  Slippery Slopes and the Angle of Repose | STEM Activity

  However, if the slope angle gets too steep, the materials will start to slide down the slope. This critical slope angle, also called the angle of repose, is different for different materials. In this activity, you will create your own little avalanches and determine the angle of repose .

  Angle of Repose versus internal friction angle ...

  Nov 19, 2010· Angle of repose is generally very close to angle of internal friction. For soft angular particles (rock salt perhaps), repose could be a few degrees higher than what you would measure for internal friction in a triax test or direct shear test under 500 lb/ft^2 normal stress, due to particle crushing.
