t each of these parts, taking into account thescale to which the diagram is drawn, that is, the number of theindicator spring. The ordinate method of measuring the mean effective pressureis illustrated by Fig. 66. The limiting lines at right and left ofthe diagram are first drawn perpendicular to… … Fig. 66. between the upper and lower lines of the diagram is measured.Adding these lengths together, multiplying their sum by thescale of the indicator spring, and dividing by 10 will give theaverage pressure or M.E.P. To obtain the centers of the ten spaces previously mentioned, aconvenient method…
