摘要
根据材料力学中的转轴公式,提出用图解法求解截面主惯性矩和主轴方位的思想,介绍了利用AutoCAD快速求解截面的几何性质的方法。
According to the transformation equation in mechanics of materials, this paper presents the graphic method of the geomet- rical properties of a section and the situation of principal axis and another effective method about obtaining the geometrical properties of a section in AutoCAD system.
