（3）弹簧测力计由图中a位置移至b位置时，动力臂变小，而阻力与阻力臂不变，故由杠杆原理可知，弹簧测力计的拉力变大，即示数变大。
【分析】1、 探究杠杆平衡的条件 ，原理为动力*动力臂=阻力*阻力臂，首先对杠杆进行调平：调平原理为动力×动力臂=阻力×阻力臂，当指针偏左表明左侧较重，所以需要增加右侧力和力臂；调平的原因为：减小杠杆自重对杠杆平衡试验的影响；
2、其次不断改变钩码重力以及钩码的位置，记录多组试验数据，分析动力、动力臂、阻力、阻力臂的大小关系；其中动力大于阻力此时杠杆为费力杠杆，反之属于在省力杠杆；
3、最后，使用弹簧测力计对杠杆的平衡进行动态分析，改变拉力的方向，实质为改变动力臂的大小，动力臂变小，则动力变大。
（1）杠杆静止，受力平衡，故此时杠杆处于平衡状态。
（2）杠杆左端下沉，应向右调节杠杆的平衡螺母，使杠杆在水平位置平衡，便于测量力臂的长度。
（3）弹簧测力计由图中a位置移至b位置时，动力臂变小，而阻力与阻力臂不变，故由杠杆原理可知，动力变大，即弹簧测力计示数变大。
