U teorijskom dijelu rada opisana je podjela aluminijskih legura, njihove karakteristike i problematika zavarljivosti aluminijskih legura s posebnim osvrtom na primjenu aluminijskih legura u brodogradnji. Detaljno je opisan TIG postupak zavarivanja te je objašnjena klasifikacija osnovnih vrsta spojeva koji se primjenjuju pri izradi brodskih konstrukcija. U posljednjem dijelu teorijskog rada dan je pregled pripreme spojeva za zavarivanje aluminijskih legura prema normi HRN EN ISO 9692-3. U eksperimentalnom dijelu rada odabrana je tehnologija zavarivanja aluminijske legure 6082 T6. Strojnom obradom sukladno normi HRN EN ISO 9692-3 pripremljene su dvije cijevi. Provedeno je zavarivanje radnih komanda AC TIG postupkom. Naposljetku su provedena ispitivanja radiografskom metodom, statično-vlačni pokus i ispitivanje savijanjem te je izvršena makroskopska analiza. Na temelju dobivenih rezultata eksperimentalnog rada donesen je zaključak. The theoretical part of this thesis deals with the division of the aluminum alloys, their characteristics and weldability problems, with special reference to the application of aluminum alloys in shipbuilding. The TIG welding process is described in detail. Moreover, the classification of the basic types of joints used in the construction of the ship structures is explained. An overview of the preparation of joints for welding aluminum alloys according to the HRN ISO 9692-3 standard is given in the last part of the theoretical work. In the experimental part the suitable welding technology has been chosen for welding aluminum alloy 6082 T6. Two pipes were prepared by machining accordingly to the HRN ISO 9692-3. Butt welding of pipe was done using the AC TIG technology. Ultimately, tests were carried out using the radiographic method, static tensile test and bending test, along with performing macroscopic analysis. Based on the obtained results of the experimental work, a conclusion was made.

Zadatak ovog završnog rada je konstruirati dizalicu sa svrhom podizanja i spuštanja u more jedrilica do 1800 kilograma. Dizalica mora biti oblikovana tako da omogućava prihvat jedrilica s jarbolom i stabilizatorom te ih može prenijeti iz mora na prikolicu. Prihvat jedrilice se ostvaruje trakama, a dizalica je pričvršćena za betonsku podlogu. Kroz prvi dio rada provedena je analiza postojećih konstrukcijskih izvedbi dizalica za brodove i njihovih radnih principa te su predložena četiri koncepta. Provedena ja evaluacija koncepata te je odabrana optimalna varijanta s kojom se krenulo u daljnju razradu. U drugom dijelu rada proveden je analitički proračun svih kritičnih dijelova konstrukcije te je na posljetku izrađen 3D CAD model i odgovarajuća tehnička dokumentacija. 3D modeliranje i izrada tehničke dokumentacije napravljena je u programskom paketu SOLIDWORKS. The assignment of this final thesis is the design of crane with purpose of lifting sail boats up to 1800 kg from the sea and lowering them to the sea. The crane must be designed so it enables grabing of sail boats with mast and stabilizer and so it can transfer them to the trailer. The grabing of sail boat is achived with flat webbing slings and the crane is fastend to concrete base. Through the first part of the thesis, analysis of the existing solutions of cranes for boats and their operating principles is conducted. Also four concepts are proposed. After the evaluation of concepts was made, the optimal variant was chosen which is used in the further elaboration. In the second part of thesis, analytical calculation of all critical parts of construction was made and finally, 3D CAD model with corresponding technical documentation was made. 3D modeling and production of technical documentation was made in SOLIDWORKS software package.

U ovom se radu nastojalo objasniti kako su teleskopski sustavi izvrsna retencijska sredstva kod protetske rehabilitacije djelomične bezubosti. Indikacija je svakako kod pacijenata s malim brojem preostalih zuba jer osiguravaju pravilan prijenos žvačnih sila na zub. Uz to, ostvaruje se odlična stabilizacija, retencija te zadovoljavajuća estetika donje trećine lica. Period adaptacije je puno kraći u odnosu na ostala retencijska sredstva zbog sigurnog ležaja u usnoj šupljini. Nastavlja se pisati o vrsti teleskopskih sustava, njihovim dijelovima, indikacijama te mehanizmu rada. Objašnjava se uloga teleskopskog sustava kod djelomične proteze, prednosti i nedostatci. U nastavku rada piše se o samoj svrsi izrade djelomične proteze u usnoj šupljini. Objašnjava se plan i postupak same izrade djelomične proteze. In this study attention is on telescopic systems as excellent retentive agents in prosthetic rehabilitation of partial toothlessness. The indications are certain in patients with a small number of remaining teeth. Along with that, excellent stability, retention, and satisfactory aesthetics are achieved in the lower third of the face. The adaptation period is much shorter compared to other retention agents due to a secure bearing in the oral cavity. Mainly, the study speaks about the type of telescopic systems and their indications, the mechanism of operation and parts of the telescopic system itself. Moreover, the role of telescopic system in partial prosthesis, advantages and disadvantages is explained. Also, the study explains the purpose of making a partial denture in the mouth cavity. Nevertheless, it explains the plan and the process of making a partial denture itself.
