1:1  06-28[物理]李老师教你处理滑轮组的基本方法
推荐理由：同学初始学习的滑轮有动滑轮和定滑轮两种，对于单一的动滑轮或定滑轮的题目不是很难。但是在实际出现的题目中还会出现两种滑轮同时存在的情况，在解决此类问题时，同学们可能会觉得有困难，下面李老师将教你通过对每一个滑轮单独进行受力分析，利用我物体平衡时合力为零的特点列出各力之间的关系，进行解答。 讲解人：http://www.jiandan100.cn/teacher/9179f6592cd148639d529dbe03746659/ ，北京物理高级教师。长期执教毕业班，把关中考物理。 题面：如图所示，物体C重100N，在不计摩擦和绳重的情况下，要匀速提起重物时，需加力F为28N，若滑轮的规格都相同，则每个滑轮的重为N。
