We give a statistical-mech. theory of stress transmission in disordered arrays of rigid grains with perfect friction. Starting from the equations of microscopic force and torque balance we derive the fundamental equations of stress equilibrium We illustrate the validity of our approach by solving the stress distribution of a homogeneous and isotropic array.
