 Requirements:

Credit conditions  participation in exercises at least 70%,
Exam: fulfillment of credit conditions, demonstration of knowledge corresponding to the lectured material in the form of a written test containing both theoretical questions (three) and numerical examples (three). The written test will be evaluated by points. The student can get 0.5 or 1 point from each answer. To obtain E, a min. number of 3 points, 5 or more points are needed to get A. In the case of an ambiguous classification level, an oral exam will follow.
The questions for the exam are from the following areas:
Statics and dynamics, volume and crosssectional characteristics, material properties and material tests, theory of strength and elasticity.
Questions related to numerous examples correspond to the examples given in the scripts of Selected Chapters from Experimental Biomechanics (Kutílek, Žižka).
