| Course abstract | |
| Students will acquire knowledge on durability, stiffness and stability of materials for calculation of constructions a, develop engineering perception, supporting on the theory they study to put into practice the substantiation of optimal structural design of constructions of food production machinery. | |
| Learning outcomes and their assessment | |
| Knowledge - students comprehend the basic principles of engineering calculation on strength, stability and deformation of materials and constructions – interactive tests and two tests.
Skills - using the methods and modes of the strength of materials students are able to perform practical calculations on strength, stability and deformation of engineering constructions – practical works. Competence - students are able to solve technical problems and perform independent calculation and selection of appropriate machinery for food processing – 3 homeworks. |

| Requirements for awarding credit points | |
| Course assessment with a mark is formed follows:
• all homework must be submitted and successfully graded. The homeworks include mechanical load and strength problem solving (40%) • all interactive tests must be submitted and successfully graded. The tests include multichoice, numerical, interaction via text and figures in the environments of Moodle and Kahoot. Grading in Moodle is automated(20%) • two classroom tests must be written and successfully graded (40%). |
|
| Description of the organization and tasks of students’ independent work | |
| The problems for independent work are similar to the ones given during practice work. The problem starts with statement of initial parameters. To solve the problem, application of the skills obtained during practice is necessary. | |
| Criteria for Evaluating Learning Outcomes | |
| The test with a mark is formed as the weighted mean of the results of interactive tests, homeworks, and classroom tests. | |
