Competences |
| Students understand the general function and necessity of gearboxes. They are familiar with the technical jargon of the subject area and have a basic understanding of the physical boundary conditions. Furthermore, they will be able to calibrate a bending beam with applied strain gauges as a force sensor and use it to measure force in a model car. They will also be able to apply the momentum theorem to an accelerated linear motion, measure forces on a model car in a wind tunnel and determine the drag and lift coefficients.
The students are able to analyze, evaluate and comprehensibly explain structures of lightweight construction with regard to stability failure due to buckling by calculation and experiment. Furthermore, the students are able to calculate the overall efficiency of an electro-mechanical system (electrically driven model car under load). Students are familiar with the main causes of losses that occur in the process in question.
