The guidelines contain the necessary theoretical information and practical material for the calculation of statically defined farms using the capabilities of the Mathcad mathematical package. On a specific typical example, the procedure for performing laboratory work on the calculation of a statically defined farm . is analyzed in detail. In order to consolidate the material at the end of the manual, individual tasks are offered for self-fulfillment. The work is intended for students of construction specialties who continue to study the possibilities of using modern computer technologies to solve computational problems in construction mechanics. The method of solving such problems can be used by senior students to conduct various calculations of structures in the form of farms, as well as in the performance of research and development, course and diploma design.
