Side 384 - When a straight line standing on another straight line makes the adjacent angles equal to one another, each of the angles is called a right angle ; and the straight line which stands on the other is called a perpendicular to it.
Side 400 - AB of the circle into as many equal parts as the polygon is to have sides. With the points A and B as centers and radius AB, describe arcs cutting each other at C.
Side 387 - A circle is a plane figure contained by one line, which is called the circumference, and is such, that all straight lines drawn from a certain point within the figure to the circumference are equal to one another : 16. And this point is called the centre of the circle.
Side 393 - A cone is a solid figure described by the revolution of a right-angled triangle about one of the sides containing the right angle, which side remains fixed.
Side 392 - A prism is a solid figure contained by plane figures, of which two that are opposite are equal, similar, and parallel to one another ; and the others parallelograms.
Side 393 - The diameter of a sphere is any straight line which passes through the centre, and is terminated both ways by the superficies of the sphere.
Side 399 - Let AB be the straight line to be divided into a certain number of equal parts: From the points A and B, draw two parallel lines AD and BC. at any convenient angle with the line AB. Upon AD and BC set off one less than the number of equal parts required, as Al, 1-2, 2-D, etc. Join Cl, 2-2, 1-D, the line AB will then be divided into the required number of equal parts.
Side 292 - Horse-Power Constant of an engine is found by multiplying the area of the piston in square inches by the speed of the piston in feet per minute and dividing the product by 33,000. It is the power the engine would develop with one pound mean effective pressure. To find the horse-power of the engine, multiply the MEP of the diagram by this constant.
Side 390 - A Tangent is a straight line which touches the circumference but does not intersect it, however far produced. The point in which the tangent touches the circumference is called the Point of Contact, or Point of Tangency. 171. DEF. Two Circumferences are tangent to each other when they are tangent to a straight line at the same point.
Side 406 - Let ACBD be the given circle: Draw the diameters AB and CD at right angles to each other. With any convenient radius and centers A, C, B and D describe arcs intersecting each other at E, H, F and G. Join EF and GH which form two additional diameters. At the points AB and CD draw the lines KL, PR, MN and ST, parallel with the diameters CD and AB respectively.
