　　是由不同的材料导体装在有绝缘材料的金属套管中，被加工成可弯曲的坚实组合体。铠装电缆包括铠装热电偶、铠装热电阻、铠装加热器和铠装引线，主要用于化工、冶金、机械制造、发电和科学试验等的温度测量、信号传输及特殊加热，用量大的是铠装热电偶。

作用于同一刚体上的大小相等，刚体上大小相等，方向相反但不共线的两个平行力组成的力系，称为力偶。力偶为矢量，力偶是一种只有合转矩（所有转矩的总合），没有合力的力系统。它又称为纯转矩。作用于物体，力偶能够使物体完全不呈现任何平移运动，只呈现纯旋转运动。作用在刚体上的两个或两个以上的力偶组成力偶系。简单的力偶是由两个大小相等，方向相反的力构成的，力偶的国际单位是N.m。若力偶系中各力偶都位于同一平面内，则为平面力偶系，否则为空间力偶系。
