INTRODUCTION

The purpose of this publication is to provide part-time students with a working program and control tasks for the course of general physics.

All educational material of the course program is divided into three parts:

1. "Mechanics, molecular physics and thermodynamics".

2. "Electrostatics. Direct current. Electromagnetism".

3. "Optics. Physics of the atom and atomic nucleus".

Each part contains: a work program, a list of educational literature, examples of problem solving, training tasks, control tasks, reference tables.

The distribution of the volume of classes and types of educational work in the study of physics for part-time students of all specialties is given in Table. one.

Table 1

The main form of studying the discipline is the student's independent work on the recommended literature. It is advisable to work through the material using examples of problem solving, training tasks, control tasks, reference tables.

The proposed book presents a course of lectures on two sections of technical mechanics - "Theoretical Mechanics" and "Strength of Materials". Each section contains options for practical exercises on the main topics. This manual can be used for self-study of the discipline "Technical Mechanics", in particular in distance learning, as well as in preparation for exams and tests.

The textbook is written in accordance with the state educational standard, is intended for students of technical schools and colleges, and can also be recommended to university students.

Publisher: Stroyizdat

Genre: Construction, renovation, Education, Mechanics

The main axioms of statics in the action of forces on a perfectly rigid body and the laws of plane displacement of a point and a rigid body are stated. Methods for calculating the most elastically deformable ordinary systems operating under the criteria of tension, shear, torsion, bending and their general impact are given. Methods for calculating multi-span statically defined and indefinite beams and frames, three-hinged arches, flat trusses, retaining walls are given. The theoretical provisions of the explained material will be accompanied by samples from construction practice.

Genre: Education, Mechanics

Tasks for settlement-analytical and settlement-graphic works on all sections of the course of technical mechanics are given.

Guide to solving problems in theoretical mechanics.

Publisher: Vysshaya Shkola

Genre: Education, Mechanics

The manual has selected standard problems throughout the course of theoretical mechanics, uniform guidelines and recommendations for solving problems. Problem solving will often be accompanied by thorough explanations. However, many problems are solved in several ways. The manual is intended for students of correspondence and evening technical schools and has the task of giving them support in obtaining initial skills in solving problems in theoretical mechanics. The allowance is used, among other things, by students of daytime technical schools.
