Page 59 - 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 64 - 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 61 - In order to obtain accurate measurements each degree is divided into 60 equal parts called minutes and each minute into 60 equal parts called seconds.
Page 63 - 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 129 - H with two faces parallel to V; the diagonal from the front upper right-hand corner to the back lower left-hand corner is indicated by the dotted line. Swing the cube around until the diagonal is parallel with V as shown in the second position. Here the front face is at the right. In the third position the lower end of the diagonal has been raised so that it is parallel to H, becoming thus parallel to both planes. The plan is found by the principles of projection, from the elevation and the preceding...
Page 65 - Fig. 4. Ellipse. The ellipse is a curve formed by the intersection of a plane and a cone, the plane being oblique to the axis but not cutting the base. If a plane is passed through a cone as shown in Fig. 1 or through a cylinder as shown in Fig 2, the curve of intersection will be an ellipse. An ellipse may be defined as being a curve generated by a point moving in a plane, the sum oj the distances of the point to two fixed points being always constant.
Page 91 - O' as a center and a radius of £ inch draw a circle, and tangent to it draw the indefinite horizontal straight line A B. Divide the circle into any number of equal parts (12 for instance) and through these points of division C, D, E, F, etc., draw horizontal lines. Now with the dividers set so that...
Page 141 - OBLIQUE PROJECTIONS. In oblique projection, as in isometric, the end sought for is the same — a more or less complete representation, in one view, of any object. Oblique projection differs from isometric in that one face of the object is represented as if parallel to the vertical plane of projection, the 'others inclined to it. Another point of difference is that oblique projection cannot be deduced from orthographic projection, as is isometric. In oblique projection all lines in the front face...
Page 136 - The right-hand edge of the bottom shows the width, the left-hand edge the length, and the vertical edge the height. The short edges of the cover are not isometric lines, hence are not shown in their true lengths; neither is the angle through which the cover is opened represented in its actual size. The corners of the cover must then be determined by coordinates from an end view of the box and cover. As the end of the cover is in the same plane as the end of the box, the simple end view as shown in...
