Page 247 - CIRCLES. A circle is a plane figure bounded by a curved line, every point of which is equally distant from a point within called the center. The curve which bounds the circle is called the circumference.
Page 250 - A sphere is a solid bounded by a curved surface, every point of which is equally distant from a point within called the center.
Page 249 - A cone is a solid bounded by a conical surface and a plane which cuts the conical surface. The plane is called the base and the curved surface the lateral area.
Page 261 - P as a center and any convenient radius (about 2£ inches) draw the. indefinite arc ED cutting the line A C. Now with the same radius and with D as a center, draw an arc P Q. Set...
Page 344 - ... water, leaving a white copy of the ink drawing on a blue background. If running water cannot be used, the paper must be washed in a sufficient number of changes until the water is clear. It is a good plan to arrange a tank having an overflow, so that the water may remain at a depth of about 6 or 8 inches. The length of time to which a print should be exposed to the light depends upon the quality and freshness of the paper, the chemicals used and the brightness of the light. Some paper is prepared...
Page 343 - If the erased line is to have ink placed on it, such as a line crossing, it is better to use a soft rubber eraser. All moisture should be kept from the cloth. Blue Printing. The tracing, of course, cannot be sent into the shop for the workmen to use, as it would soon become soiled and in time destroyed, so that it is necessary to have some cheap and rapid means of making copies from it. These copies are made by the process of blue printing in which the tracing is used in a manner similar to the use...
Page 248 - The area of the lateral faces is called the lateral area. The altitude of a prism is the perpendicular distance between the bases. Prisms are triangular, quadrangular, etc., according to the shape of the base.
Page 343 - This coated paper, or blue-print paper, as it is called, is laid on the padded surface of the frame with its coated side uppermost; the tracing laid over it right side up, and the glass pressed down firmly and fastened in place. Springs are frequently used to keep the paper, tracing, etc., against the glass. With some frames it is more convenient to turn them over and remove the backs. In such cases the tracing is laid against the glass, face down; the coated paper is then placed on it with the coated...
