[updated 15.04.2024]
Applicability / Curricular relevance:
All study programs (with year of the version of study regulations) containing the course.

MAB_19_A_2.03.GBD (P241-0253) Mechanical and Process Engineering, Bachelor, ASPO 01.10.2019 , semester 2, mandatory course
MAB_24_A_2.03.GBD Mechanical and Process Engineering, Bachelor, SO 01.10.2024 , semester 2, mandatory course
Workload:
Workload of student for successfully completing the course. Each ECTS credit represents 30 working hours. These are the combined effort of face-to-face time, post-processing the subject of the lecture, exercises and preparation for the exam.

The total workload is distributed on the semester (01.04.-30.09. during the summer term, 01.10.-31.03. during the winter term).
60 class hours (= 45 clock hours) over a 15-week period.
The total student study time is 150 hours (equivalent to 5 ECTS credits).
There are therefore 105 hours available for class preparation and follow-up work and exam preparation.
Recommended prerequisites (modules):
MAB_24_A_1.02.TMS Engineering Mechanics - Statics
MAB_24_A_1.03.WSK Materials Science with Lab Exercises

Learning outcomes:
After successfully completing this module, students will be able to:
 
- name and understand the basic load cases by being able to apply them in different contexts in order to recognize their significance for structural strength.
 
- apply real components to mechanical models and abstract them by developing solutions to better understand complex relationships.
 
- identify, analyze and calculate the behavior of components under the basic loads by performing safety verifications in order to be able to assess component dimensions.
 
- dimension simple components under different loads by analyzing practical applications to determine the required component dimensions.
 
- formulate questions in front of a larger group and actively contribute to the discussion by promoting the learning process through interactive discussions and group work.
