根据已知条件,需要求算木杆秤的支重两点间的距离时,随着具体情况不同,已知条件不一样,就有不同的计算公式。在杆秤制造修配工作中,最常见的一种情况,是在制造新秤时,已知铊重、杆重、最大秤量以及最大秤量时力点与重点的位置,需要求重点与支点间的距离,以确定支点的位置。另外一种情况是在杆秤修配工作中出现的,即杆秤从第一刀纽处断了,需利用原来的第二纽作为修复后的第一纽,这时已知铊重、杆重、最大秤量以及最大秤量时力点与支点间距离,需要求支点到重点 According to known conditions, the need to calculate the distance between two points of the wooden weigher, with different conditions, known conditions are not the same, there are different formulas. In the manufacture and repair of bar scales, the most common case is that when creating a new scale, it is known that heavy and heavy thallium, the maximum weight, To determine the location of the fulcrum. Another situation is in the rod scale repair work appears, that is, from the first pole knife pole off, need to use the original second New Zealand as the first repair after New York, then known thallium weight, rod weight, maximum Weighing and the maximum capacity of the distance between the force point and the fulcrum, you need to ask the fulcrum to focus
