Let C be a curve in a plane and let L be a line not parallel to that plane. Then the set of points on lines parallel to L that intersect C is called a cylinder. The straight lines that make up the cylinder are called the rulings of the cylinder. In the sketch, we have the generating curve, a parabola in the yz-plane: The line L is the x-axis. The rulings are parallel to the x-axis. rulings.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
