Description
Version: 3.0 start 01 February 2024
Short description
Students learn to calculate stresses due to bending in simple and composed cross-sections and to determine the bending lines of statically determinate and indeterminate single and multi-field beams as well as to calculate stresses and deformations due to torsion. Finally, an introduction to the topic of transverse shear in case of bending is given.

Remarks
1. This module requires mastery of the matters of the classes Analysis 1 and 2, Algebra and Statistics 1 and 2 as well as Statics and strength of materials 1.
2.
The lecturers in MFL2 jointly create a end-of-semster exam that is the same for all classes. The lecturers create the midterm exams individually, but coordinate them with each other with respect to the level of difficulty.
Legal basis
The module description is part of the legal basis in addition to the general academic regulations. It is binding. During the first week of the semester a written and communicated supplement can specify the module description in more detail.
