阅读本刊2013年第2期的《对一道奥赛题的拓展》一文(以下称文[1]),发现文中对圆盘所受摩擦力大小的计算方法有误、结果错误,故对此问题做进一步的研究和说明.文[1]中所研究的是这样一道拓展的奥赛题:如图1所示,平而薄的均质圆盘,质量为m,半径为R,放在水平桌面上,圆盘绕过中心O的竖直轴以角速度ω顺时针旋转,同时O点相对桌面水平运动的速度为v0,圆盘与桌面间的
Read the article, Issue 2, 2013, “Development of an Orsay Question” (hereinafter referred to as the text [1]), found in the paper disc friction suffered by the size of the calculation method is wrong, the result is wrong, so the problem For further research and clarification, the Orsay problem explored in [1] is as follows: As shown in Figure 1, a flat and thin homogeneous disk of mass m and radius R is placed on a horizontal table top , The disc around the center O of the vertical axis of the angular velocity ω clockwise rotation, at the same time O-level desktop relative to the horizontal motion speed v0, between the disk and the desktop
