The results are shown that: 1) under an equivalent moving concentrated force, dynamic responses of the simply supported beam consist of steady response and transient response.

研究结果表明：1）等效移动集中力作用下，简支梁的动力响应由稳态响应和瞬态响应组成。

It came from three words. Dynamic,meaning a force.

And so, you know from your Newtonian mechanics, as you were learning in 8.01, the dynamic force here mv^2/r is mv squared over r.

在8。01节对牛顿动力学系统的学习中，我们可以知道这里的运动受力,就是。

I am going to say if that electron is to stay in its orbit, that is to say it doesn't flee the atom, it doesn't collapse under the nucleus then the sum of the forces on the electron must be zero No net force. And so that will be the sum of a dynamic force plus an electrostatic.

如果电子会保持在它的轨道上运行,既不脱离原子的话，它就不会由于原子核对它的吸引力而被瓦解掉,电子所受的合力一定为零,由于没有合力,所以电子所受力为动态力和静电力的总和。

"We now have leapt up a step to become a space-power nation, " he said, adding that South Korea would use this "overwhelming moment as a strong, dynamic force" to help drive an independent space programme.
