英语翻译The simple fact shows that the more of the force of friction is got rid of,the farther will the ball travel,and we are led to infer that,if all the impeding forces of gravitation and resistance could be removed,there is no reason why the ball,once in motion,should ever stop. ...
Chapter 4 – The Friction Force, F frictionAlan HendricksonColin BuckhurstMechanical Design for the Stage
attrition, detrition, grinding - the wearing down of rock particles by friction due to water or wind or ice adhesive friction, traction, grip - the friction between a body and the surface on which it moves (as between an automobile tire and the road) resistance - any mechanical force that...
aThe forces due to friction are called friction force 力量由于摩擦称摩擦力[translate]
The first type is described by the coefficient of sliding friction fs, which is the dimensionless ratio of the frictional force to the normal load; the second is described by the coefficient of rolling friction fr, which is the ratio of the rolling frictional moment to the normal load. ...

of the asphalt pavement structure. There is obvious stress concentration in the mixture in contact with the sensor flange and the sensor’s force measuring rod, which leads to fatigue cracking of the beam specimen and reduces the fatigue life of the mixture. Under repeated loads, the formation ...
On frictional faults, sliding and cycles of quiescence and seismic activity are described by rate-and-state laws relating the coefficient of friction \(\mu\) to an evolving interface state and the sliding velocity37. Seismogenic sliding arises as an instability when friction decreases with increasing...
