of the ropeon the sides of the groove. Consider the small length of arcof the rope subtending the angle da, and let Q denote the re-sisting pressure at each side of the groove in contact with therope. We have the static equation 2 Q sin 0 = i? = 2 r sin — = Tda. (See Art. 9, p. 224.) The measure of… … Fig. 7. in which 6 is half the angle between the sides of the groove.As the groove angle is usually about 45 degrees, the value of dis 22.5 degrees, and cosec 6 = 2.6. 230 THE ELEMENTS OF POWER TRANSMISSION TThen log-7 = 2.6^0;, in which 11 is the coefficient of friction and a the arc of contactof…
