【摘要】 传统的旋转体体积求法是通过对坐标的积分求得,借助数学和物理的方法推导出一个脱离坐标系的旋转体体积公式,利用这个公式,用悬线法测出均匀转面的重心,就可求出旋转体体积,并在生活和生产中得到广泛的应用.更多还原

【Abstract】 The traditional volume of rotating object is worked out through integral of coordinates.In this paper,a formula of volume of rotating object is derived by a mathematical and physical method without a coordinate system.As long as we measure the gravity center of a uniform rotation plan with the hanging line method,the volume of the rotating object may be obtained easily.And then it can be applied to daily life and production.更多还原
