Description
Version: 2.0 start 01 February 2020
Short description
Students learn to calculate the deflection curve of statically determined and statically undetermined single span and multi field beams, together with stresses and deformations resulting from torsional loading. Students are introduced to the concepts of equivalent stresses and energy methods.

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.
