Abstract
Tema obrade završnog rada je geometrijska nepromjenjivost statičkih sustava. Prilikom proračuna, potrebno je ustanoviti statičku stabilnost sustava. Pokazat će se što znači kada je sustav statički neodređen ili određen, što znači stupanj slobode te koji kriteriji moraju biti zadovoljeni kako bi se sustav smatrao geometrijski nepromjenjivim. Dovoljni i nužni uvjet su uvjeti prema kojima se definira geometrijska promjenjivost. Ovisno o načinu proračuna, nužni uvjet se za statički neodređene sisteme određuje na drugačiji način, odnosno radi li se o metodi sila ili metodi pomaka. Stupanj neodređenosti se po metodi sila izražava preko geometrije sustava, npr.broj krutih veza, broj reakcija, štapova itd. Po metodi pomaka se definira ovisno o tome koliko ima nepoznatih pomaka, translatornih ili rotacijaskih. Koliko je sustav neodređen definiran je time koliko veza je potrebno dodati da bi isti bio određen. Oba načina će biti prikazana i pojašnjena na primjerima. Primjeri na kojima će se prikazati nepromjenjivost su ravninski i prostorni sustavi.
Abstract (english)
The topic of the final paper is the geometric indeterminate of static systems. When calculating, it is necessary to establish the static stability of the system. It will be shown what it means when a system is statically indeterminate or determinate, what a degree of freedom means, and what criteria must be met in order for a system to be considered geometrically invariable. A sufficient and necessary condition are the conditions according to which the geometric variability is defined. Depending on the method of calculation, the necessary condition for statically indeterminate systems is determined in different ways, ie whether it is a method of forces or a method of displacement. The degree of uncertainty is expressed by the method of forces through the geometry of the system, eg the number of rigid bonds, the number of reactions, rods, etc. The method of displacement is defined depending on how many unknown displacements, translational or rotational. How indeterminate a system is is defined by how many connections need to be added for it to be specified. Both ways will be shown and explained by examples. Examples to show immutability are planar and spatial systems.
