The paper discusses the role and influence of the geometric equation of deformation of elastic rod mechanics in the modeling of statics, and explains similarities and differences between this deformation equation and nonholonomic constraint in analytical dynamics. It is indicated that only the solutions of the equation satisfying the physical conditions of the rod are meaningful. The conclusions are also valid in the condition of elastic rod dynamics.
