1.如图1所示,某小组同学利用DIS实验装置研究支架上力的分解.A、B为两个相同的双向力传感器,该型号传感器在受到拉力时读数为正,受到压力时读数为负.A连接质量不计的细绳,可沿固定的板做圆弧形移动.B固定不动,通过光滑铰链连接长0.3m的轻杆将细绳连接在杆右端O点构成支架.保持杆在水平方向,按如下步骤操作:
1. As shown in Figure 1, a group of students using the DIS experimental device to study the decomposition of stent force .A, B for the two two-way bi-directional sensor, the type of sensor readings received by the tension is positive, when the pressure reading Negative. A connection quality cords can be made along the fixed plate circular arc movement .B stationary, through the smooth hinge connection 0.3m long light bar will be connected to the string at the right end of the rod O points constitute the bracket. In the horizontal direction, proceed as follows:
