近年来各省市中考常涉及有关固体压强的考题,这里对试题类型及其解法作些归纳介绍。 一、由具体的压力及受力面积求压强 这类试题的特点是,题中常设置一些多余数据,如面积或力。若概念不清,便会受其迷惑,造成解题的失误。 解此类题的关键是正确确定解题公式P=F/S中的F及S. In recent years, provincial and municipal entrance examinations often involve questions on solid pressure. Here, the type of questions and their solutions are summarized. First, the specific pressure and stress area for pressure The characteristics of such questions is that often set some redundant data, such as area or force. If the concept is not clear, it will be confused and cause mistakes in solving problems. The key to solving such problems is to correctly determine the F and S in the solution formula P=F/S.
