阅读下面短文并回答问题(请注意问题后的词数要求).

    Let children judge their own work. A child learning to talk

does not learn by being corrected all the time:if corrected too

much, he will stop talking. He notices a thousand time a day the

difference between the language he uses and the language those

around him use. Bit by bit, he makes the necessary changes to

make his language like other people's. In the same way,children

learning to do all the other things they learn to do without being

taught to walk, run, climb, whistle, ride a bicycle, compare(比

较) their own performances with those of more skilled people,and

slowly make the needed changes. But in school we never give a

child a chance to find out his mistakes and correct them for

himself. We do it all for him. We act as if we thought that he would

never notice a mistake unless it was pointed out to him,or corrcet

it unless he was made to. Let him work out,with the help of other

children if he wants it,what this word says,what the answer is to

that problem, whether this is a good way of saying or doing this or

not.

      If it is a matter of right answer,  as it may be in mathematics

of science, give him the answer book. Let him correct his own

paper. Why should our teachers waste time to do such routine

work?  Our job should be to help the child when he tells us that he

can't find the way to get the right answer. Let the children learn

what all educated persons must some day learn, how to measure

their own understanding, how to know what they know or do not

know.

如图所示,重力不计的杠杆OAB,可绕O点在竖直平面内转动。重力为100N的物体挂在OA的中点处。已知OA=40cm,AB=30cm,OA垂直于AB,杠杆与转动轴间的摩擦忽略不计。要使杠杆平衡,且OA段处于水平位置,那么作用于B端的最小力的力臂等于       cm,最小力的大小等于       N。
