Fig. 2 shows the intersection of two equal cylindricalsurfaces at right angles to each other, as in the case of apipe elbow. When two cylinders having equal diametersintersect, and their axes also intersect, the front elevation of INTERSECTIONS Al. Fi^.ll. J-AJrVARV /4, /e3!^ For notice of copyright, see page
