resultant与resulting的区别
resultant: caused by the thing that has just been mentioned因而发生的,因此而产生的
resulting它只是动词的进行时态
Resultant force
Resultant force is just the vector sum of individual forces. If you do this by geometry
you just arrange each force vector one after the other
with their magnitude and direction preserved. The resultant force can be then be found by pleting the vector (force) polygon with a (resultant) force vector
with the head of which coincides with the head of the first force vector and the tail coincides with the tail of the last force vector. The "parallelogram of forces" is just a specific application of the above principle when there are only o force vectors. An alternative
and more easy and convenient
way of dealing with force addition is to resolve individual force into X and Y ponents(i.e. ponent pointing along the X and Y axis of the Cartesian Coordinate System). Then
find the algebraic sum of the ponent forces in the X and Y directions separately. Finally
use Pythagous Theorem and trigonometry method to determine the magnitude and direction of the resultant force. Example
given force A of magnitude 10 N at angle 30 degrees above the X-axis. Force B of magnitude 20 N at angle 60 degrees above the X-axis. Sum of force ponent along X-direction = 10.cos(30) + 20.cos(60) N = 18.66 N Sum of force ponent along Y-direction = 10.sin(30) + 20.sin(60) N = 15 N hence
magnitude of resultant force = square-root above the X-axis
resultant force是什么意思
resultant force
英
n. 合力; 总作用力;合力点
全部释义》》
The formation of resultant force of department leading group in universities results from clear-cut responsibility, cooperation add harmony.
高校系级领导班子合力的形成,来源于明确职责,相互配合,协调一致;
net force是什么
我个人的理解:
在大多数情况下两个是可以通用的.但是net force 有净力的意思,也就是说,是合外力,各个方向上的合外力;
而resultant应该是可以表示单独某个方向上的合力.
resultant是什么意思
resultant
英
adj. 因而发生的,结果必然产生的;组合的,合成的
n. 结果,后果;合力,合成力,合成 合矢量:等价于一组向量的一个单个向量
