At some point, said Ross s. Stein, a geophysicist with the geological survey, "the stress overwhelms that friction," and a rupture occurs.
到了某个点，“压力压倒了摩擦力，”进行这次地质勘察的地球物理学者Ross s . Stein说，然后断裂就产生了。

The friction force is each meshing point cut off resistance.
摩擦力就是各个啮合点被剪断时的阻力。

Through calculating friction factor and operating point of pump or fun of two examples on fluid mechanics, methods using solver and curve-fitting in EXCEL were introduced.
