RT Journal Article SR Electronic A1 FILÍPEK, Josef A1 NAVRÁTIL, Miroslav T1 DYNAMIC VISUALIZATION AND CALCULATION OF STRESSES DURING BENDING AND TORSIONAL LOADING JF Trends in education YR 2009 VO 2 IS 1 SP 420 OP 423 UL https://tvv-journal.upol.cz/en/artkey/tvv-200901-0096.php AB The paper uses animation to show the course of normal tension of a bent girder and shear tension of a twisted rod. For the derivation of strength equations with the use of high mathematics a number of idealized assumptions must be applied. The authors endeavour to show that even relatively complicated technical problems can be presented clearly and comprehensibly to students.
