Mechanics I – MaschinenbauCopyright: Martin Braun
Mechanics is the branch of physics that adresses the effects of forces and moments on material bodys.
In Stereostatics, the bodies loaded by forces or moments are considered as RIGID, i.e. they do not change their shape under the effects of forces or moments.

How does the event work?
While the focus of the plenary lecture is on imparting theoretical content, the latter are used in the plenary exercises to solve engineering problems. The plenary exercises are offered in German and English language.
The examination of the module is taken in electronic form on the computer. It is offered on
several dates during the semester vacation. The grade of an examination that has already been
passed can be improved by increasing the total number of points by a maximum of 6 bonus
points, which can be earned in bonus point tests during the semester.

Home exercises to acquire bonus points
In accordance with the valid examination regulations of the Bachelor's programme in Mechanical Engineering, a total of six points can be earned by passing the homework exercises. The points earned will be added to the total number of points if the student passes the examination. In case of non-participation and failure to pass the exam, the bonus points earned in the summer semester remain valid in the following winter semester. After that (in the next summer semester) the bonus points expire and must be acquired again.
There are three home exercises offered, in each of which up to two points can be earned. There are no half points. Each homework consists of several questions that are randomly selected from a list of questions. From 33 % of the points in the homework there is one bonus point and from 66 % of the points there are two bonus points for the exam.
The processing time of the homework exercise is 20 minutes each and can only be processed in fixed time windows after logging in to the OPS (access data is available in the L²P learning room).
The time windows are open on the following fixed dates, from 12 noon to 12 midnight:
