eare the limiting rays, and the arc FH is that which caststhe required shadow. Take any point q on fh and draw qp, the plan of a raythrough Q. This ray is intercepted by the surface of thecylinder at a point on the generator whose plan is p; drawthe elevation of this generator, and through q draw… … not forgetting to determine the important points /, s, gand the highest point on the curve. (See the remarkstowards the end of the last problem.) The elevation of theshadow on the shank is the curve spgi. The line of separation consists of two detached portions,each closed, viz.
