## Geometry to determine the center of gravity of uniform polygonal thin plate

• 摘要: 物体重心位置的掌握对于很多情况下控制物体的平衡和稳定性十分重要. 对于工程实际中遇到的一些薄板状构件, 如何快速确定其重心位置?使用解析法需确定很多点的坐标, 计算耗时耗力；使用试验方法(悬挂法)很多情况下不现实；本文给出一种快速确定多边形均匀薄板重心位置的几何法.

Abstract: It is very important for controlling the objects’ balance and stability that to grasp the center of gravity position in many cases. For some of the actual sheet-like structures, how to quickly identify the location of its center of gravity? Analytical method using the coordinates of many points to be determined is time-consuming and labor-intensive; using the test method (suspension method) in many cases is unrealistic; In this paper presents a geometry to quickly determine the center of gravity location of the uniform shin polygon.
