Goal
  • The purpose of mastering the discipline "Engineering mechanics and resistance of materials" is to train specialists with fundamental knowledge in the field of natural science and engineering mechanics to work in the field of engineering and construction.
Objective
  • Tasks of the discipline: - acquisition of skills in creating mathematical models in nature and technology and analytical analysis of the solutions found; - acquisition of skills in calculating elements of buildings and structures for strength, rigidity and stability; - study of mechanical properties of structural materials.
Learning outcome: knowledge and understanding
  • The state and prospects of development of the theoretical foundations of machine science, the importance of this discipline in engineering practice.
Learning outcome: applying knowledge and understanding
  • Modern methods for calculating bending with torsion, methods for calculating statically indeterminate problems based on examples of calculating flat rod models, determination of internal forces, stresses, deformations and displacements in structural elements.
Learning outcome: formation of judgments
  • Each student must have a formed judgment on the topic of his specialty.
Learning outcome: communicative abilities
  • Conduct a conversation- dialogue in any language, use the rules of speech etiquette.
Learning outcome: learning skills or learning abilities
  • To form in the conditions of real production the principles of choosing the directions of optimization of technologies and properties of materials products and structures.
Teaching methods

interactive lecture (application of the following active forms of learning: guided discussion or conversation; moderation; demonstration of slides or educational films;) - construction of scenarios for the development of various situations based on the specified conditions; - information and communication; - search and research (independent research activity of students in the learning process); - solving educational tasks.

Assessment of the student's knowledge

Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.

Excellent Good Satisfactory Unsatisfactory
Mandatory classroom attendance, participation in the discussion of issues, preliminary preparation for practical classes on the teaching materials of the discipline and basic literature, timely completion of the tasks of the SIW and SIWT and their delivery, participation in all types of control (current control, control of SIW and SIWT, intermediate control, intermediate attestation). Completed the laboratory work in full compliance with the necessary sequence of actions; in response, correctly and accurately performs all tasks, graphic drawings; correctly performs error analysis. When answering questions, he correctly understands the essence of the question, gives an accurate definition and interpretation of the basic concepts; accompanies the answer with new examples, is able to apply knowledge in work; can establish a connection between the studied and previously studied material, as well as with the material learned in the study of other disciplines. I fulfilled the requirements for the "5" rating, but 2-3 shortcomings were made. The student's answer to the questions satisfies the basic requirements for the answer to 5, but is given without applying knowledge in a new situation, without using connections with previously studied material and material learned in the study of other disciplines; one mistake or no more than two shortcomings are made, the student can correct them independently or with a little help from a teacher. I did not complete the work completely, but not less than 50% of the volume of laboratory work, which allows me to get the correct results and conclusions; mistakes were made during the work. When answering questions, the student correctly understands the essence of the question, but in the answer there are separate problems in the assimilation of the course questions that do not prevent further assimilation of the program material; no more than one gross error and two shortcomings were made. Completed the laboratory work in full compliance with the necessary sequence of actions; in response, correctly and accurately performs all tasks, graphic drawings; correctly performs error analysis. When answering questions, he correctly understands the essence of the question, gives an accurate definition and interpretation of the basic concepts; accompanies the answer with new examples, is able to apply knowledge in work; can establish a connection between the studied and previously studied material, as well as with the material learned in the study of other disciplines.
Evaluation form

The student's final grade in the course is calculated on a 100 point grading scale, it includes:

  • 40% of the examination result;
  • 60% of current control result.

The final grade is calculated by the formula:

FG = 0,6 MT1+MT2 +0,4E
2

 

Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;

E is a digital equivalent of the exam grade.

Final alphabetical grade and its equivalent in points:

The letter grading system for students' academic achievements, corresponding to the numerical equivalent on a four-point scale:

Alphabetical grade Numerical value Points (%) Traditional grade
A 4.0 95-100 Excellent
