Static load test of the support structure
Chytil, Jan ; Žítt, Petr (referee) ; Daněk, Petr (advisor)
Subject of the thesis is experimental verification of load capacity of construction for storage coal by using load test. In the first part, the analysis of sorts of load tests is made and its execution in causality with standard regulations. Further possible options of bringing test load are described and also the method of evaluation of static load test. Second part looks into the analysis of means of measurement which can be used to determine required quantity. Final part is dedicated to realization and evaluation of the load test on material construction followed by comparison of experimental values with values established on a model of construction created by using computing program.

Description of physical characteristics of the C1 forward stroke in selected elite canoe slalom athletes
Foukal, Pavel ; Bílý, Milan (advisor) ; Busta, Jan (referee)
Title: Description of physical characteristics of the C1 forward stroke in selected elite canoe slalom athletes Objectives: The aim of this study was to describe the physical characteristics of a forward stroke in C1 using strain gauge measurement among selected elite canoe slalom athletes during flatwater paddling, and to organize the obtained results into a clear format. Methods: We used a single-axis foil strain gauge attached to each tested person's paddle and an accelerometer (G-link 200) positioned at the front of the boat to obtain the data. Everything was connected to a data acquisition unit (V-link 200). We processed the data using the Sensor Connect software developed by Lord Microstrain. Results: We have been able to describe the basic physical characteristics of the forward stroke on the dominant and non-dominant side as well as the cross stroke. It turns out that a greater force applied in the stroke does not necessarily lead to a faster resultant time for a given segment. Similarly, a higher frequency of strokes does not automatically lead to faster and better times. Boat speed is not dominantly determined by any of the physical indicators of the stroke cycle studied, but is probably determined by a combination of them, related to other factors such as the shape of the boat, the...

Involvement of the arms during ski-mountaineering according to different slope inclinations.
Zemanová, Markéta ; Jindra, Matouš (advisor) ; Gnad, Tomáš (referee)
Title of the thesis: Involvement of the arms during ski-mountaineering according to different slope inclinations. Objectives: The objective of the bachelor thesis is to find out the difference of strain makes to poles during ski-mountaineering depending on slope and constant speed. Methods: The study is designed like a pilot study. 8 persons were chosen for this measurement. It was an experiment. The research was realized in a laboratory. Results: Results of study confirm our scientific question. Pressure in the poles increased when the angle of slope is increasing during ski- mountaineering. Angle 10ř of slope showed at an average 42,3% more pressure makes to poles than angle 0ř. Angle 20ř of slope showed at an average 12,8% more pressure makes to poles than angle 10ř. Key words: Ski-mountaineering, strain-gauge transducer, pressure
