| 1. | Each of circular dishes is subjected to the action of a tangential force .
每个圆盘都受到切向力的作用。 |
| 2. | A-form pylons are designed to withstand earthquake forces .
A型框架式塔架设计中考虑塔架能够经受地震力的作用。 |
| 3. | In other words, zero resultant force is equivalent to no force at all .
换句话说，合力为零就相当于没有任何力的作用。 |
| 4. | If only conservation forces act, the kinetic energy plus the potential energy remains constant .
如果只受保守力的作用，则动能加势能是一个恒量。 |
| 5. | If a body's motion is changed to a new direction, a force has been applied sideways .
如果物体的运动改变到另一个新的方向，那么它必定受到一个斜向的力的作用。 |
| 6. | These loads are normally applied by hydraulic jacks acting directly at the point of application of the force .
通常这些荷载是用液压千斤顶直接施加于力的作用。 |
| 7. | There is an exceptional case, three forces with paralleled lines of action, which will be discussed in chapter 3 .
三个力的作用线相互平行的例外情况，我们将在第三章讨论。 |
| 8. | The motion that results when forces act on a material system depend also on mass distribution in the whole system .
物体系统受到力的作用所产生的运动也取决于在整个系统中的质量分布。 |
| 9. | If a body is deformable, as all are to some extent, the deformation depends upon the point of application of the force .
如果一物体是可以变形的（所有物体都或多或少可以变形），那么这种形变就取决于力的作用点。 |
| 10. | A - form pylons are designed to withstand earthquake forces
