It has sometimes been found that the groove walls, under the combined action of superheated steam and friction, in cases where actual running contact has occurred, have worn very considerably, the wear taking the form of a rapid crumbling away. It is possible, however, that such deterioration may be due solely to the quality of the steel from which the spindle is forged.
First, that the long friction, the press campaign, the rivalry of economic and political interests, had contributed largely to the European tension. Secondly, that in spite of that, the question did get settled, and by diplomatic means. On this subject, at any rate, war was not "inevitable."
Finally, then, as far as we can judge, the tail has disappeared in man and the anthropomorphous apes, owing to the terminal portion having been injured by friction during a long lapse of time; the basal and embedded portion having been reduced and modified, so as to become suitable to the erect or semi- erect position.
The stones were broken into a thousand pieces in their course, their angles rubbed down, and their surfaces polished by friction, and this vast bed of rubble measures near the mouth of the Rhone some sixty feet in depth, and extends under the blue surface of the sea to the distance of many miles.
Friction is the condition for the transformation of all kinds of mechanical motions into heat. The test of the amount of friction is the rate of loss of motion. A top will spin some time in the air because its point is small.
It may be remarked here, in passing, that giant steam-jets rushing through the orifices of the earth's crust constitute an enormous hydro-electric engine; and the friction of ejected materials striking against each other in ascending and descending also generates electricity, which accounts to some extent for the electrical condition of the atmosphere.
They had now persuaded themselves that without a national assembly it would be impossible to oust the clique of clansmen who monopolized the prizes of power. Between the men in office and these visionary agitators a time of friction, more or less severe, ensued.
Although the skin appears as though it could resist all friction, it is astonishing how quickly a sore becomes established, and how difficult this is to heal. The mahouts are exceedingly careless, and require much supervision; the only method to ensure attention is to hold them responsible and to deduct so many rupees from their pay should the backs of their animals be unsound.
And, probably, not the students alone, but all the casual and constant visitors of Yama experienced in greater or lesser degree the friction of this inner psychic heart-sore, because Doroshenko did business only late in the evening and night, and no one lingered long in his place but only turned in in passing, half-way on the journey.
Men and women alike accept this notion; the serious essayist and philosopher, as well as the novelist and paragrapher, reflect it in their pages. The force of inertia acts in the domain of psychics as well as physics; any idea pushed into the popular mind with considerable force will keep on going until some opposing force or the slow resistance of friction stops it at last.
