Nastavne materijale priložene u okviru ovog Web dnevnika treba koristiti kao dopunu nastavnih materijala sakupljenih pažljivim slušanjem i zapisivanjem informacija na časovima redovne nastave mehanike i otpornosti materijala koja se realizuje u Tehničkoj školi iz Smedereva, u okviru obrazovnog profila "Mašinski tehničar za kompjutersko konstruisanje" i "Tehničar za kompjutersko upravljanje".</p> <p>P.S.<br /> Iskreno Vam želimo da mehaniku i otpornost materijala lako savladate i da ovi predmeti za Vas postanu zanimljivi u ovoj školskoj godini</p> <p>Predmetni nastavnici:</p> <p>Vera Mitrašinović<br /> Aleksandar Jovanović</p> mehanika 2026-05-14T19:14:11Z http://mehanika.blog.rs/blog/mehanika/otpornost-materijala/2012/05/29/primer-upotreba-cae-koncepta-u-otpornosti-materijala <p><object type="application/x-shockwave-flash" width="450" height="350" data="http://www.youtube.com/v/6JiYZH8RzA4" id="ltVideoYouTube"><param name="movie" value="http://www.youtube.com/v/6JiYZH8RzA4" /><param name="wmode" value="transparent" /><param name="allowScriptAcess" value="sameDomain" /><param name="quality" value="best" /><param name="bgcolor" value="#FFFFFF" /><param name="FlashVars" value="playerMode=embedded" /></object></p><p>Proračun i konstruisanje elastične linije -
