PT Journal AU FILIPEK, J NAVRATIL, M TI DYNAMIC VISUALIZATION AND CALCULATION OF STRESSES DURING BENDING AND TORSIONAL LOADING SO Trends in education PY 2009 BP 420 EP 423 VL 2 IS 1 DE flexion and torsion; normal and shear tension; cross-section module; animated presentations. 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. ER
