TWO CYLINDERS INTERSECTING .\T OTHERTHAN .\ RIGHT ANGLE. Fig. 140 is the side elevation of twocylinders intersecting at other than a rightangle or forming an acute angle, acutemeaning less and obtuse meaning greaterthan a right angle. It is immaterial whatangle these cylinders occup) to each other,nor the difference, if any, in the diameters,only that the intersecting cylinder be thesmaller. If the method given be same radius from // as a center, draw thecircle in Fig. 142 at any point upon theline A B where it will not come in con-tact with the other figure. Draw the centerline H I J right angles to A /?, andfrom / draw a semi-circle. Space off thesemi-circle, in each figure into 11 ordinates through these points par-allel to the center lines ; and numberingthem, start with No. i at the top in , and end with No. 11 on the In Fig. 142, start with No. i at thetop or highest part of the shell, and rundown to No. 6 on the side ; then start withNo. 6 on the opposite side and end withNo. 11 at the top. Mark the depth theordinates encircle the cylinder in Fig. 141,by the same method used in Figs. 136 and137, by drawing lines parallel to CD, cut-ting through the point where the ordinates 231 it is midway of the length or opposite thestraight seam.
