小华与小强在探究杠杆的平衡条件时进行了如下操作,并对相关问题进行了探讨: (1)实验一开始,小华把杠杆的中点支在支架上,通过调节平衡螺母使杠杆平衡于水平位置.调节过程中小华问小强:“你知道我这样做的目的吗?”小强回答道:“这是为了让杠杆的重力作用线通过支点,使杠杆的重力不会对自身的水平平衡产生影响.”可是小华认为小强的说法不够全面,并说这种做法的另一目的是为了“方便”.你认为这里小华所说
Xiao Hua and Xiao Qiang conducted the following operations when exploring the balance conditions of the lever and discussed related issues: (1) At the beginning of the experiment, Xiaohua supported the midpoint of the lever on the support and balanced the lever by adjusting the balance nut. In the horizontal position, during the adjustment process, Xiaohua asked Xiaoqiang: “Do you know the purpose of my doing this?” Xiaoqiang replied: “This is to make the lever’s gravity pass through the fulcrum so that the lever’s gravity will not be balanced against its own level. Have an impact.” But Xiaohua thinks that Xiaoqiang’s statement is not comprehensive enough, and that another purpose of this approach is to “convenience”. You think Xiaohua said here.
