force couple

The simplest example of a force couple consists of two equal and opposite forces.

力偶最简单的例子包含两个大小相同、反向相反的力.

a force couple can be transferred anywhere in its plane of action freely.

力偶可以在其作用面内任意移动,而不影响它对刚体的作用效应.

is very small, the force couple of resistance is neglected in most engineering problems, hence the rolling friction is neglected.

由于滚阻系数很小，所以在工程中大多数情况下滚阻力偶不计，即滚动摩擦忽略不计。

Fluid Force Couple Hydraulic Variable Pump/ Motor

液力平衡式变量液压泵/马达

Grain rotation which produces crack on the grain boundary was caused by force couple because slip is obstructed and stress concentrated on the grain boundary;

滑移在品界受阻产生应力集中并产生力偶使晶粒发生相对转动，从而在品界产生裂纹；
