Subject aims expressed by acquired skills and competences
Students will acquire methods that can be used to obtain information about the operating load of machine parts, especially from the point of view of information needed for strength and lifetime calculations of machine parts. The student will be able to realize a simple experiment to analyze local stresses of machine parts, as well as simple types of sensors of mechanical values, especially forces, torques, pressure. It will also gain an idea of the possibilities of internal stress analysis in the material. The student will be able to analyze the technical measurements in terms of accuracy and validity of the obtained results.
