The volume is devoted to the mechanics of rods, which is a branch of the mechanics of deformable bodies. The main goal of the book is to present systematically theoretical fundamentals of the mechanics of rods as well as numerical methods used for practical purposes. The monograph is concerned with the most general statements of the problems in the mechanics of rods. Various types of external loads that a rod may be subject to are discussed. Advanced techniques that includes vector analyses, linear algebra, and distributions is used in the derivation of linear and nonlinear equilibrium equations. The use of these techniques helps us to make transformations and rearrangements of equations more transparent and compact. Theoretical basics of rods interacting with external and internal flows of fluid and the derivation of the formulas for the hydrodynamic and aerodynamic forces are presented.
