Learning outcomes of the course unit

Summary of present experimental methods for measuring of mechanical quantities which are necessary for examination of machines behavior. The basic knowledge’s and experience from problems. The students will obtain ability to formulate requirements for these tasks in specialized workplaces. They will by also able to evaluate and interpret their results.

Prerequisites

Basic knowledge of analogue and digital engineering, measurement of electrical and non-electrical quantities, mathematical statistics, mechanics of bodies.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Assesment methods and criteria linked to learning outcomes

Course-unit credit requirements: active participation in the seminars, good results of elaborated laboratory exercises, solving additional tasks in case of longer excusable absence. Examination – combined (written and oral). In written part students have to prove knowledge of basic terms, important principles and their application; in the oral part the discussion over written part and records from laboratory exercises follows. None of these must be evaluated by the failing degree F.

Aims

The course objective is to make students familiar with current methods, instrumentation and computing technique for determination of input data which are necessary for computer modelling of machines and their elements and results verification.

Specification of controlled education, way of implementation and compensation for absences

Attendance at seminars is required. One absence can be compensated by attending a seminar with another group in the same week, or by working out of substitute assignments. More absences are compensated by additional assignments according to the instructions of the tutor.
