sentedby Pt, and if a is the crank angle from the dead point, andb the angle of the connecting rod, we have I\ = Pr sin (a -f- b) = P sin (a 4- b) cos b (57) 150 LOCOMOTIVE OPERATION. Expanding equation 57, we obtainsin a cos b -j- sin b cos a Pt=P cos b fsin a cos b sin b cos a+ cos b cos b Now if… … and cos b = V I sin a r therefore, by substituting these values, we ob-tain Pt=P sm a cos a sin a -|- Vi sm a (58) all angles being in terms of the crank angle. rBut as — sin a is generally verv small, we r can neglect this term and write equation 58simply Pt=P sin a -f — sin a cos aJ (59) STEAM…
