Although I here use the formulae as given by Rankine, I am sorry to say that I am unable to recommend their acceptance with that faith which mathematicians claim for their mystic symbols. These formula proceed on the assumption of perfect flexibility, the calculation proceeding by integration of resultant pressures on infinitely small elements of the arc of contact. There is a possibility that the speed of running the belt may affect the accuracy of the assumption of perfect flexibility. A belt which may be assumed to be perfectly flexible for the purposes of an experiment made with the surfaces at rest and when there is time for the two surfaces to come intimately in contact, may when run at a high velocity, and bent and unbent rapidly as it runs, be less completely in contact with the pulley, and this may, along with differences introduced by rise in temperature, produced by the rubbing of the two surfaces slipping relatively to one another, help to account for the differences in the co-efficient of friction which have been shown to exist in the American experiments referred to. The errors arising from these causes are not, however, fatal. We shall see later on when we come to speak of the strength of belting that a first approximation arrived at by the method which we have adopted will be sufficiently accurate for practical purposes, and that if any slipping takes place in a belt transmission designed on this basis we have plenty of margin in the strength of the belt to permit of an increase in the tension so as to get the resistance required. It will be found as a general rule that the assumption of so low a friction co-efficient will ensure a satisfactory result Having then determined the tension in the driving and f...
