惯性量的几何求法及截面特殊点讨论

The Geometrical Method of Determining Inertial Moments and Products and the Discussion on the Special Points at a Section

    摘要
  • 摘要: 本文提出计算截面惯性矩、惯性积的几何方法———作惯性圆法,该法具有直观、方便、简洁的优点.讨论了惯性圆退化为一点的特殊情形,就任意截面确定了截面特殊点的位置.

     

    Abstract: This paper puts forward a geometrical method of determining inertial moments and products——drawing the inertial circle,which is straight,convenient and simple.It discusses a special case that the inertial circle becomes a point,and determines the places of the special points at any general section.
