內容簡介

In the preparation of this volume we were fortunate to receive advice from C. Berning， P. Deift， V. Enss， G. Hagedorn， J. Holder， T. Ikebe， M. Klaus， S. Kuroda， J. Morgan III， S. Pinault， J. Rauch， S. Ruijsenaars， and L. Smith. We are grateful to these individuals and others whose comments made this book better.

學和流體力學從力學分齣後，餘下的部分組成一般力學。一般力學通常是指以質點、質點係、剛體、剛體係為研究對象的力學，有時還把抽象的動力學係統也作為研究對象。一般力學除瞭研究離散係統的基本力學規律外，還研究某些與現代工程技術有關的新興學科的理論。

根據力的平行四邊形則作圖，可以看齣，力F1和F2的閤力F的大小和方嚮隨著F1和F2之間的夾角而變化。當夾角等於0度時，力F1和F2在同一直綫上且方嚮相同，F=/F1/+/F2/(/為絕對值符號)，閤力的大小等於兩個力的大小之和，閤力的方嚮跟兩個力的方嚮相同。當夾角等於180度時，力F1和F2在同一直綫上但方嚮相反，F=F1-F2，閤力的大小等於兩個力的大小之差，閤力的方嚮跟兩個力中較大的那個力的方嚮相同。

如果有兩個以上的共點力作用在物體上，我們也可以應用平行四邊形定則求齣它們的閤力：先求齣任意兩個力的閤力，再求齣這個閤力跟第三個力的閤力，直到把所有的力都閤進去，最後得到的結果就是這些力的閤力。
