Stress, strength and strain analysis of the crane truss construction.
Nedělka, Pavel ; Borák, Libor (referee) ; Vrbka, Jan (advisor)
This bachelor thesis deals with stress, strength and strain analysis of the plane crane truss construction. The aim of this work is the calculation of forces for the simple frame with the help of joint equilibrium equations. These forces will be modified by further construction treatment. This treatment turns the simply frame into the hyperstatic system. The obtained values data are the input data for the design of geometry of particular bars. The unknown dimensions will be determined by two strenght limit states. These limits are: limit state of elasticity and limit state of stability. Then we will make the strain analysis. It will determine the displacement in the action of the force, the effect of actual clearance as well as the brace failury effect to the construction safety. Further will be determined the influence of the weight of the construction to the strenght.

Lift positional table
Solovský, Jakub ; Kašpárek, Jaroslav (referee) ; Pokorný, Přemysl (advisor)
This bachelor thesis is focused on functional strength calculation of scissor lift mechanism, which serves for transporting loads of a weight 500 kg situated on a pallet. Required lift height is from the first position 0,75 m to the second 2,5 m above the ground. There are mentioned engineering design, calculation of roller conveyor drive, dimension of lifting mechanism and concept of linear hydraulic motor in particular parts of the thesis. Other part of this thesis is drawing documentation.

Strength design and deformation analysis of the truss construction.
Ryšánek, Michal ; Nedělka, Pavel (referee) ; Vrbka, Jan (advisor)
This Bachelor thesis is focused on strength design and strain-stress analysis of truss construction. Simplified as a plain truss construction. One of the main goals of this thesis is calculate stresses for each member of the construction, depending on the load position. The cross section of beams were designed respecting safety conditions. The influence of the gravity field was not taken into account.

Stress and deformation analysis of railway bridge over the Odra River
Svoboda, Josef ; Profant, Tomáš (referee) ; Fuis, Vladimír (advisor)
This bachelor thesis deals with strain, stress and deformation analysis of the planar truss bridge construction. The aim is to determined the size of axial forces for statically determinate system and then making construction changes to reduce axial stresses in the individual beams in the structure. This structural modification becomes statically indeterminate structure. To solve this problem we consider different positions of the train at the bridge. The obtained values we can use to assess stress and deformation of the structure and the analytical results will be compared with the results obtained using the finite element method.

Strength design of the truss construction
Rašovská, Hana ; Horníková, Jana (referee) ; Vrbka, Jan (advisor)
Bachelor thesis deals with strength, stress and strain analysis of the plain truss construction. The aim of the thesis is calculation the size of forces for two storage of the system with resultant suggestion of the cross- section geometry. The different position of the load is also considered. Further the influence of gravitational field of the Earth is reviewed as well as displacements in characteristic places, in construction is defined.

Strain, stress and strength analysis of the frame construction.
Hrubý, Jaroslav ; Vlk, Miloš (referee) ; Vrbka, Jan (advisor)
This work deals with the stress and strain calculation as well as with the safety evaluation at the plane (2-D) frame loaded by the individual force F. The aim of this work is not acquiring the use of cutting-edge computer programs to determine the stress and deformation, but to learn how to use practically the basic calculation methods being taught at the subject Strength of materials to get practical experience with the application of these calculation methods.

Competitive Balance of First and Second Football Leagues in Selected European Countries
Radimský, Marek ; Šíma, Jan (advisor) ; Opelík, Daniel (referee)
Title: Competitive balance in first and second football leagues in selected European countries. Objective: The aim of this work is to identify competitive balance in first and second football leagues in selected European countries and compare them with each other. Methods: This thesis calculates static competitive balance using the standard deviation of percentage winnings. Results: The results show that in most football leagues there is a gradual decline in competitive balance, especially in the first leagues. In the group of second leagues, there is smaller amount of competitions with decreasing competitive balance. Second competitions were also on average more balanced compared to the first leagues in all countries included in the research. Last but not least, the results also overly show that the first leagues from less developed countries in football such as the Czech Republic, Poland or Croatia are more balanced compared to the first leagues from richer and more developed countries in football such as England, Germany, Spain or Portugal. Key words: competitive balance, football leagues, static balance, football, standard deviation

Competitive Balance the of selected football leagues in Europe, their development and comparison
Mráček, Václav ; Šíma, Jan (advisor) ; Procházka, Jan (referee)
Title: Competitive Balance of the selected football leagues in Europe, their development and comparison. Goals: Determining the competitive balance in the six top European football competitions. This is a Czech Gambrinus liga, Dutch Eredivisie, German Bundesliga, Austrian Bundesliga, Ukrainian Premier liha Hungarian OTP liga, compare to competition and an outline of the development trend. Methods: The standard deviation of percentage wins, correlation coefficient, the presentation of results based on percentages, graphs, trends. Results: All results are presented in the analytical part of the work, verify predetermined hypotheses and are an important source of comparison for each event and outline trends. Keywords: Competition, equilibrium, European football league, football league, static balance, dynamic balance, season, club, reform, UEFA, sport, decreased balance, standard deviation, correlation coefficient.

Evaluation of competitive balance in top European football leagues
Vichr, David ; Šíma, Jan (advisor) ; Novotný, Jiří (referee)
Title: Evaluation of competitive balance in top European football leagues Objectives The quality of objective of this bachelor thesis is the analysis of competitive balance of four European football leagues. Namely the Czech league, the Danish league, the Sweden league and the Norwegian league, their comparison and subsequent comparison with other European leagues. Methods: Static competitive balance calculated using the standard deviation of percentage wins. Results: The results show comparison of competitive balance in top European leagues and their development trends. As well as combine examined competitions into groups by similar development trends. Key words: Football, competition, static balance, standard deviation
