The ordinates y are measured in feet, and thecomponent h is measured in pounds; hence, the bending momentis expressed in foot-pounds. If the reactions had been determined algebraically, themagnitude-direction diagram could have been drawn and closed;locating the point /, before the location-direction diagram wasdrawn. It would then have been possible to have chosen apoint on a horizontal line through / for the pole o, (Fig. 560).In this case the location-direction 0/ becomes a horizontal lineas shown in Fig. 566; and the bending moment at any sectionequals 10 lb. times the number of feet scaled on the correspond-ing ordinate in the location-direction diagram. It has beenshown that the shear at any section may be obtainedfrom the magnitude-
