A worker wishes to pile a cone of sand onto a circular area in his yard. The radius of the circle is r,and no sand is to spill on to the surrounding area. If mu is the static coefficient of friction between each layer of sand along the slope and the sand, show that the greatest volume of sand that can be stored in this manner is (1)/(3) pi muR^(3) .

Sand is piled up on a horizontal ground in the form of a regualr cone of a fixed base of radius R .The coefficient of static friction between sand layers is mu .The maximum volume of sand that can be piled up, without the sand slipping on the surface is

Sand is pilled up on a horizontal ground in the form of a regular cone of a fixed base radius R. The coefficient of static friction between sand layers is mu. The maximum volume of sand that can be pilled up, without the sand slipping on the surface is
