摘要
基于合力矩定理分解的思想和合力矩定理解析式的应用两个方面,对合力矩定理作了一些归纳和总结,例举说明了定理在力学中的"无所不能"的作用:利用其分解的思想直观方便求力矩,力偶;利用解析式求平面任意力系、空间任意力系、空间平行力系合力的作用线位置.
Based on the idea of decomposition of resultant moment theorem and the application of analytical formula of resultant moment theorem,this paper sums up the theorem of resultant moment,and illustrates the omnipotent function of the theorem in Mechanics:it is intuitive and convenient to find moment and couple by using its decomposition thought;and it is used to calculate the resultant force of plane arbitrary force system,spatial arbitrary force system and spatial parallel force system line position.
