20． 测量力臂 左 仅凭一次实验的数据得出的结论具有偶然性 向远离支点方向移动
【知识点】探究杠杆的平衡条件的实验装置和操作步骤、探究杠杆的平衡条件的实验结论和数据处理
【详解】(1)[1]当在杠杆上挂物体时，杠杆在水平位置平衡，力臂在杠杆上，便于测量力臂，同时消除了杠杆自重对杠杆平衡的影响。
[2]在调节杠杆平衡时，杠杆右端低左端高，要使杠杆在水平位置平衡，应将杠杆左端的平衡螺母向左端调节。
(2)[3]只有一次实验总结实验结论是不合理的，一次实验很具有偶然性，要多进行几次实验，避免偶然性。
(3)[4]要使跷跷板转动，可采取的做法是：男孩不动，女孩向远离支点方向移动（或者女孩不动，男孩向靠近支点方向移动；或者女孩不动，男孩蹬地，减小男孩对跷跷板的压力）。
21．（1）98N；（2）19.6N，水平向左；（3）10.4N
