Querschnittsfläche
-
Beispielsätze:
- Im Querschnitt der Kerbe konzentriert sich die Spannung, weil dort die Querschnittsfläche kleiner als im ungestörten Querschnitt ausfällt.
- Bei Bauteilen aus zusammengesetzten Querschnittsflächen kann mit dem Steinersche Satz die Flächenmomenten der Gesamtquerschnitte bestimmt werden.
- Dazu sind zuerst die Koordinaten (in y- und z-Richtung) Querschnittsflächen-Schwertpunkts zu bestimmen, welche als Flächenmomente erster Ordnung bezeichnet werden.
cross-sectional area
Description:
The stress is concentrated in the notch's cross-section, because the cross-sectional area is smaller there than that of the intact cross-section. In the case of components comprising composite cross-sectional areas, the parallel-axis theorem can be used to determine the area moments of the total cross-sections. To do so, it is first necessary to determine the coordinates (in y- and z-directions) of the centre of gravity of the cross-sectional area, which are called the first moments of area.
