The manual outlines a new method for calculating statically definable and statically indeterminate rod and plate systems for static and dynamic loads, as well as for stability. A large number of typical tasks and examples with brief instructions for solving them are given. A significant place is given to the mathematical formulation of problems and their solution with the help of personal computers. For students, graduate students and teachers of higher technical educational institutions, specialists in the field of mechanics of deformable solid and construction mechanics .
