The error can be eliminated by multiplying the measured resonant frequency or the calculated Young's modulus by a correction coefficient. Some formulae for the correction coefficients as well as a new formula are presented and compared with the ASTM formulae</dc:description><dc:description xml:lang="sl">Enostavna enačba, dobljena iz poenostavljene diferencialne enačbe upogibnega nihanja za primer z enakomernim prerezom, nam ne da točne vrednosti Youngovega modula oz. hitrosti zvoka, če je razmerje dolžine in premera (oz. dolžine in debeline) vzorca manjše od 20. Napako lahko odpravimo z množenjem izmerjene resonančne frekvence ali izračunanega Youngovega modula s popravnim količnikom. V prispevku predstavljamo nekaj enačb za popravne količnike in novo enačbo ter jih primerjamo z enačbami Ameriškega združenja za preizkušanje in materiale (American Society for Testing and Materials - ASTM)</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-I3WPN0CF"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-I3WPN0CF" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-I3WPN0CF/0ac2af1e-6523-43e4-88c9-354d26d4e272/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Univerza v Ljubljani, Fakulteta za strojništvo</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-I3WPN0CF/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-I3WPN0CF" /></ore:Aggregation></rdf:RDF>
