A brief summary of the theory of the main calculation questions: determination of reactions of connections of constructive elements, assessment of the tense state of details and constructive elements, kinematic analysis of the simplest mechanisms included in the cycle of general engineering disciplines : "Theoretical Mechanics", "Material Resistance", "Machine Details" and "The Theory of Machines and Mechanisms". The main techniques and methods of work in the Excel tabular processor for performing such calculations. A detailed description of the implementation of the most characteristic examples of calculations of structural elements and parts of technological equipment in the Excel tabular processor. is given. The manual is intended for the preparation of bachelors in the direction of 35. 03. 06 Agroengineering .
