Der Einfluss der Abmessungen lässt sich am einfachsten am einseitig<br />
eingespannten Biegebalken erkennen (<xr id="fig:Oneside_fixed_contact_bending_spring"/><!--(Fig. 6.20)-->). Unter der Voraussetzung<br />
kleiner Auslenkungen ergibt sich folgende Beziehung:<br />
:<math>F = \frac{3 \cdot E \cdot J}{L^3} </math><br />
<br />
wobei das Trägheitsmoment des rechteckigen Balkenquerschnitts ist<br />
:<math>J = \frac{B \cdot D^3}{12}</math><br />
<br />
Für Federn mit kreisförmigem Querschnitt gilt<br />
:<math>J=\pi D^4/64</math><br />
:<math>D= Durchmesser</math><br />
<br />
Um eine plastische Verformung der Feder zu vermeiden, darf die Biegespannung<br />
F<sub>max</sub> nicht überschritten werden.<br />
:<math>\sigma_{max} = \frac{3 \cdot E \cdot D}{2L^2}\cdot_{max}</math><br />
<br />
Die Grenzbelastung wird durch die Federbiegegrenze bzw. die 0,2% - Dehngrenze (R<sub>p0,2</sub>) bestimmt<br />
:<math>\times_{max} = \frac{2 \cdot L^2}{3 \cdot D \cdot E}R_{p0,2}</math><br />
<br />
<br />bzw.<br /><br />
:<math>F_{max} = \frac{B \cdot D^2}{6L}R_{p0,2}</math><br />
