th respect to the motion of the pencil point.Thus, if a spring is a 60 lb. spring, it means that the pencil 160 THERMODYNAMICS point moves over a distance of 1 inch for a change in pressure, onthe piston, of 60 lbs. per square inch; and a distance of 0.75 inchesfor a change in pressure of 45 lbs.… … Fig. 25. turn is connected by means of some mechanism, to the cross-head of the engine, in a manner such that the angular displace-ment of the drum is proportional to the linear displacementof the piston of the engine. The linear displacement of thesurface of the drum, however, is less than that of…
