求高手帮帮忙 专业外语要考试了 还有这么多不会呢 小弟这次能不能及格就靠各位兄弟姐妹了 为表诚意财富值全部散尽~
无知者就不要恼人清净了~
1.Equate to zero the moment about one point and the force sums in two directions. This is the approach of Eqs.(2a,b).
2.Equate to zero the moment sums about two points and the force sum in a direction that is not perpendicular to the line connecting the two chosen points.
3.Equate to zero the moment sums about three points that are not collinear.
4.A particle will remain at rest or move with constant speed along a straight line, unless it is acted upon by a resultant force.
5.When a resultant force is exerted on a particle, the acceleration of that particle is parallel to the direction of the force and the magnitude of the acceleration is proportional to the magnitude of the force.
6.The force exerted on one particle by another is equal and opposite to the force exerted by the first particle on the second.
7.The motion of a rigid body consists of a superposition of two movements.The first part consists of a movement of all points following the motion of an arbitrarily selected point in the body. The second movement is a rotation about the selected point in which all lines rotate by the same amount.
8.As mentioned previously, the dynamic effect,I.e.,the influence of inertia forces on the process of stress development in a body, depends on the dynamic loading conditions. These are quasi-static states of stress, vibrations, and stress waves. The limits between these groups are not clearly defined, however, and frequently the phenomena associated with more than one group can occur in the same dynamic event .
我不要金山词霸翻译出来的！驴唇不对马嘴！
哎 我们学的居然这么难 这么多天了连百度上都没有人会？？？ 后天就考试了…… 不知道是我们学的这么高端，还是百度上连个高手都没有
二楼 俺不是辽工大的 OVER！
哎 百度啊 你也不是万能的……

Answer 1

6．(1)Equate to zero the moment about one point and the force sums in two directions. This is the approach of Eqs.(2a,b).
对某点的力矩的和，和在俩个方向上力的和等于零
(2) )Equate to zero the moment sums about two points and the force sum in a direction that is not perpendicular to the line connecting the two chosen points.
对两点的力矩的和，和在一个方向上力的和等于零，这个方向与所选的两点的连接不垂直
(3)Equate to zero the moment sums about three points that are not collinear.
对不共线的三点的力矩的和等于零
7．(1)A particle will remain at rest or move with constant speed along a straight line, unless it is acted upon by a resultant force.
一个质点，在没有受到合外力作用时，总保持静止或匀速直线运动状态
(2)When a resultant force is exerted on a particle, the acceleration of that particle is parallel to the direction of the force and the magnitude of the acceleration is proportional to the magnitude of the force.
当一个质点受到合外力作用时，质点加速度的方向与合外力的方向相平行，而且加速度的大小与力的大小成正比
(3)The force exerted on one particle by another is equal and opposite to the force exerted by the first particle on the second.
一个质点对另一个质点的作用力与第二个质点对第一个质点的作用力大小相等，方向相反
8.The motion of a rigid body consists of a superposition of two movements.The first part consists of a movement of all points following the motion of an arbitrarily selected point in the body. The second movement is a rotation about the selected point in which all lines rotate by the same amount.
一个刚体的运动有两个重叠的运动组成。第一部分包括一个所有点都跟随刚体上任意基点的平动的运动。第二部分的运动是关于几点的转动，在转动中过基点所有的线以相同的角速度转动
15.As mentioned previously, the dynamic effect,I.e.,the influence of inertia forces on the process of stress development in a body, depends on the dynamic loading conditions. These are quasi-static states of stress, vibrations, and stress waves. The limits between these groups are not clearly defined, however, and frequently the phenomena associated with more than one group can occur in the same dynamic event .
如前所述，动态力的影响，即惯性力是一个物体的应力变化过程的影响，取决于动态负载的情况，可分为三种典型现象。他们分别是（1）准静态应力状态（2）振动和（3）应力波动。这三组的界限，不是清楚地被定义的。然而，经常地联系不止一个组的现象，能发生在同一个动力学的问题中

Answer 2

.Equate零一点左右两个方向的力量，目前款项。这是均衡的做法。（甲，乙）。
2.Equate零两分，在一个方向，不是垂直线连接两个选择点力的总和时刻款项。
3.Equate零大约3点不共线，目前款项。
4，实行粒子将保持在休息或沿直线匀速移动，除非采取行动时的合力。
5.When的合力施加一个粒子，该粒子加速是平行的力的方向和加速度的大小成正比的力的大小。
6，力施加另一种粒子是平等的，对面的第二首粒子所施加的力。
7，一个刚体运动由两个movements.The第一部分叠加一个由所有点的运动后，任意选择一个点，在机构的议案。第二乐章是一对选定的其中一点，就是所有行旋转相同数额的旋转。
8.As前面提到的动力作用，也就是说，在发展过程中应力影响的机构的惯性力，取决于动态加载条件。这是半的压力，振动静态状态和应力波。这些集团之间的界限没有明确界定，然而，经常与多个组相关联的现象发生在同一个动态事件中。
