In addition to our previous work [1], a detailed analysis has been carried out for the angular dependences of all components of the pressure tensor in a wedge-shaped cavity of a solid with dispersion forces. It has been shown that the pressure tensor components satisfy the conditions of mechanical equilibrium as a function of the distance from the walls of the wedge-shaped cavity and the angular variable. Additional contributions to the pressure tensor relative to the tensor in a planar slit have been obtained in the case of small angles.
