True or false: “Shafts that have a noncircular cross section are not axisymmetric, and so their cross sections will bulge or warp when the shaft is twisted.” (This question is based on Chapter 5.6) / Waar of onwaar: "Asse wat 'n nie-sirkelvormige deursnit het nie, is nie aksimmetries nie, en hul deursnee sal dus bult of kromtrek wanneer die as gedraai word." (Hierdie vraag is gebaseer op Hoofstuk 5.6)
