Page 494 - A continuous beam is one which rests upon more than two supports. • In this Course, the continuous beam will not be discussed, as the subject requires a knowledge of higher mathematics.
Page 661 - The material will thicken and deteriorate after a number of pipes have been dipped ; fresh pitch must, therefore, be frequently added, and occasionally the vessel must be entirely emptied of its old contents and refilled with fresh pitch; the refuse will be hard and brittle like common pitch.
Page 31 - Comparatively few engineers are good mathematicians, and in the writer's opinion it is fortunate that such is the case, for nature rarely combines high mathematical talent with that practical tact and observation of outward things so essential to a successful engineer.

Page xiv - To him they are but little more than striking instances of how completely the most simple facts may be buried out of sight under heaps of mathematical rubbish.
Page vi - They will uot forget what they have learned, for they learned it j play, without any ear-pulling, spanking, or keeping in. Let their bats and balls, their marbles, their swings, &c", once become their philosophical apparatus, and children may be taught (really taught) many of the most important principles of engineering before they can read or write.

Page 414 - We nil these with oil or grease, and thus diminish friction. Since no surface can be made perfectly smooth, some separation of the two bodies must, in all cases, take place in order to clear such projections as exist on the surfaces. Therefore, friction is always more or less affected by the amount of the perpendicular pressure that tends to keep them together. The ultimate friction is the greatest frictional resistance that one body sliding over another is capable of opposing to any sliding force...
