The dimensions are to be chosen according to the last but one digit of the student code B. Required milestones: 1. Compose a scaled structural model of the beam (according to particular A and B); 2. Calculate the supports’ reactions; 3. Compose the scaled diagrams of bending moment M and shear force Q; 4. Determine the beam’ critical sections (or critical section), compose the strength condition for bending and determine the appropriate INP section with minimum material usage; 5. Compose a scaled sketch of the chosen INP section with diagrams of normal stress and shear stress , acting at the critical section(s); 6. Calculate the values of safety factor for both bending and shear and check the adequate strength of the beam; 7

(slide) Degradation of concrete is mainly caused by chemical affects such as reactions with sulfates, sea water, acids and alkalis and physical affects including frost, fire, wind and water erosion. The chemical processes are complicated and need special circumstances to react. As a result of those, concrete usually cracks. (slide) Sea water, however, may fill the pores of concrete in marine areas, which makes it even more durable. And finally, concrete usually contains steel constructions to shear strength and compensate stressed areas. (slide) But if the concrete gets damaged, the steel is also affected by corrosion. The corrosion is mainly caused by CO2 or chlorides, which can be found in sea water and road de-icing salts. To avoid these problems stainless steel and chemical admixtures should be used. (slide) That's all. Thank you for listening!

Eelised • Stable and cost-effective for high loads Generous bracket spacings allow large-area formwork units with optimal utilization of the bearing capacity. This leads to extremely economical solutions. • Economical and safe anchoring The M30/DW20 and M36/DW26 climbing cones have been designed especially for single- sided concreting using SKS/SSC in dam construction, and to allow the transfer of high tensile and shear forces into the still fresh, unreinforced concrete. The corrosion-protected cones can be re-used – only the tie rods and threaded anchor plates remain in the concrete. • Simple and flexible planning With PERI SKSF 240 and SKS 180 single-sided climbing formwork, circular structures can also be concreted without undergoing any large planning process. Even use on inclined walls is feasible without any special measures because additional concrete loads or lifting

listing, in part because Yahoo! was an early investor in Google and had a privileged view of start-up's success. As a full-ledged portal, Yahoo! offered easy access to a board range of third-party content and related services, organized into "channels" such as Autos, Finance, Games, Health, Kids, Movies, Music, Shopping, Sports and Travels. Yahoo! is also known as the third largest online recruitment sites. Even though Yahoo! has many amazing examples, they still are loosing the shear of search. The difference between Yahoo! and Google is that Yahoo! is more like a portal and Google just collects all the information and post's it on its web page. Microsoft's vision of cloud computing repeatedly changed both in name and conception but, by 2010, plans were increasingly firm. Windows Azure let developers run applications on Microsoft-hosted platforms, while Microsoft Office 2010 was slated to include an "Office Web" version accessible through a web browser. Whereas

The free body in a free body diagram is not free of constraints, it is just that the constraints have been replaced by arrows representing the forces and moments they generate. Drawing a free body diagram can help determine the unknown forces on, moments applied to, and equations of motion of, the body and thus help to analyse a problem in statics or dynamics. In analysis of structures, free body diagrams for a component of a structure or, part thereof, are used in determining shear forces and bending moments 28. Lähtudes kiiruste liitmise seadusest, tuletage seos kiirenduste vahel ja formuleerige relatiivsusprintsiip. Identifitseerige lähtevalemis olevad kiirused. Füüsikaseadustel on kõigi konstantse kiirusega (seega ilma kiirenduseta) liikuvate vaatlejate jaoks üks ja seesama kuju. Seda asjaolu nimetatakse relatiivsusprintsiibiks
The force caused by the tension of the surface is low and provokes more smaller waves. From stresses to waves Waves caused by wind are build over deep waters and energy-rich waves are build in some distance from the equator. If air is moving over water it causes a tangential stress on the surface of the water. These stresses result in a formation of waves. The turbulence in the flow of the air creates rapidly varying shear stresses and pressure fluctuations. If the oscillations are ‘in phase’ with already existing waves a furthermore in wave development occurs. If waves have reached a certain high, wind can attack them directly and causes an additional wave growth. Wave energy is a very dense form of indirect solar energy. To compare energy W
1) kahe teineteise poole suunatud jõuvektori tulemusena püütakse keha kokku pressida s.o. toimub keha lühenemine. Seda tüüpi pinget nimetatakse survepingeks (inglise k. compressive stress). 2) kahe teineteisest eemale suunatud jõuvektori resultaadina toimub keha väljavenitamine. Kehas tekivad venitus e. lahknemispinged (inglise k. tensional stress). 3) kaks paralleelset kuid vastassuunalist jõuvektorit (suunatud teineteisest mööda) tekitavad kivimites nihkepinged (inglise k. shear stress). 34. Kivimite deformatsioon. Haprad ja plastilised deformatsioonid. Kivimitele rakendatava jõu ja nendes tekkivate pingete tulemusena toimub kivimite deformeerumine (inglise k. strain), s.t. kivim muudab kuju ja mahtu. Tahkes kehas esineb kolme liiki deformatsiooni: 1) plastiline deformatsioon - deformatsioon mille tulemusena keha paindub või muudab vormi ning peale pinge eemaldamist keha ei taasta oma esialgset kuju.

Esimesed, kes juba kaua aega soovisid näha endise Kansase osariigi kuberneri tagasiastumist, olid loomulikult Vabariikliku partei esindajad. ,,Olgu ükskõik kes Obamacare eesotsas, on see täielik läbikukkumine nagunii," kritiseeris Vabariiklaste Riikliku Komitee (RCN) eesistuja Priebus Sebeliuse tagasiastumise järel.
