本章介绍了一个项目，该项目试图获取机械工程师在日常工作中所需的数学专业知识。我们研究机械工程专业的学生在最后一个学期如何完成典型任务。本文考虑的任务涉及测量转向机构关键部件中的应变和应力并处理测量数据。我们确定的一项主要资格是在小型代数模型中勤奋工作，该模型必须用应用术语进行解释。此外，将测量曲线的数学特性与转向机构的行为联系起来对于进行合理性检查和得出结论非常重要。
This chapter reports about a project that tries to capture the mathematical expertise a mechanical engineer needs in his or her daily work. We study how mechanical engineering students work on typical tasks in their final semester. The task considered in this article is concerned with measuring strain and stress in a critical component of a steering mechanism and processing the measurement data. One major qualification we identified was diligent work in a small algebraic model which has to be interpreted in application terms. Moreover, relating mathematical properties of the measurement curves to behaviour of the steering mechanism is important for making plausibility checks and for drawing conclusions.
