【题目】(2011年高考福建卷)如图1所示,一不可伸长的轻质细绳跨过滑轮后,两端分别悬挂质量为m1和m2的物体A和B.若滑轮有一定大小,质量为m且分布均匀,滑轮转动时与绳之间无相对滑动,不计滑轮与轴之间的摩擦.设细绳对A和B的拉力大小分别为T1和T2,已知下列4个关
【Subject】 (2011 college entrance examination in Fujian) As shown in Figure 1, an inextensible light string straddles the pulley and ends with objects of mass m1 and m2, A and B respectively. If the pulley has a certain size The mass is m and evenly distributed. There is no relative sliding between the pulley and the rope, and the friction between the pulley and the shaft is not counted. The tension of the string pair A and B is T1 and T2, respectively. The following four levels are known.
