Der Begriff Torsionsfeder leitet sich von dem Verb tordieren ab, was verwinden oder verdrehen bedeutet. Zum Einsatz kommen Drehst\u00e4be beispielsweise als Torsionspendel in mechanischen Uhren, als Torsionsband in Drehspulmessinstrumenten sowie als Stabilisator zur Federung von Fahrzeugen und als Gegenkraft in Sektional-Garagentoren. Die Drehstabfeder hat einen gestreckten, stabf\u00f6rmigen Aufbau und f\u00fchrt w\u00e4hrend ihres Einsatzes eine Drehbewegung durch. Wird der Stab um seine eigene L\u00e4ngsachse verdreht, entsteht so eine Schubspannung. Diese Spannung w\u00e4chst mit dem Querschnittsradius an und ist proportional zum Torsionsmoment. Die Verteilung der Schubspannung verh\u00e4lt sich im Stabquerschnitt rotationssymmetrisch. Der Verdrehwinkel ist ebenfalls proportional zum Torsionsmoment und vergr\u00f6\u00dfert sich linear mit der Stabl\u00e4nge.<\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Aplicacoes_personalizadas_de_molas\"><\/span>Aplica\u00e7\u00f5es personalizadas de molas<strong><br \/>\n<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p> Precisas de uma mola t\u00e9cnica para a tua aplica\u00e7\u00e3o espec\u00edfica?
