stP. By careful adjustmentof the length of the link sothat the jaw takes hold ofthe clutch surface, whenthe link stands nearly ver-tical, a very easy operatingdevice is secured, and thethrust P is made a mini-mum. THEORY. Eeferringto Fig. 4S in order to cal-culate the twisting mo-ment, we must… … 347 142 MACHINE DESIGN Hence we may consider that we have a force of magnitude /aPacting at the mean radiiis 11 of the chiteh surface. Tlie twistingmoment will then be : T = WIl = /xPTl. (89) deferring to equation ~>-i, wliich gives twisting moment in termsof horse-power, and putting the two…
