Page 259 - Moment of a Force. — The moment of a force with respect to a point is the product of the force multiplied by the perpendicular distance from the given point to the direction of the force.
Page 279 - If a body oscillates about an axis, then the point at which, if a blow is struck by the body, the percussive action is the same as if the whole mass of the body were concentrated at that point, is called the center of percussion. This point is located at the same point as the center of oscillation. Center Reamers. A "center reamer" is a reamer the teeth of which meet in a point.
Page 993 - Depth of Cut per Tooth The amount of metal that the successive teeth of a broach should remove, or the increase in size per tooth, depends largely upon the hardness or toughness of the material to be broached. The size of the hole in proportion to its length also affects the depth of cut, so that it is impossible to give more than a general idea of the increase in size per tooth. Medium-sized broaches for round or square holes usually have an increase of from 0.001 to 0.003 inch per tooth for broaching...
Page 295 - The time of vibration of a pendulum varies directly as the square root of the length, and inversely as the square root of the acceleration due to gravity at the given latitude and elevation above the earth's surface.
Page 274 - If a body is acted upon by several forces, it is acted upon by each of these as if the others did not exist. This is true whether the body is at rest or in motion. In other words, if two or more forces act upon a body at the same time, each produces exactly the same effect as if it acted alone; the total effect or resultant motion of all the forces may be found by a diagram in the same way as the resultant of forces is found.
Page 259 - The resultant of two forces applied at the same point, and acting in the same direction, is equal to the sum of the forces. For example, if the two forces AB and AC, one equal to two and the other equal to three pounds ,are applied at point A, then their resultant AD equals the sum of these forces, or five pounds.
Page 926 - ... instead of 280, the number being reduced because the total movement of the crank, for each indexing, is equal to its movement relative to the index plate, plus the movement of the plate itself when (as in this case) the crank and plate rotate in the same direction. If they were rotated in opposite directions, the crank would have a total movement equal to the amount it turned relative to the plate, minus the movement of the plate.
Page 369 - The principal conclusions to be drawn from the results of this research may be briefly stated as follows: 1. The length of tube, between transverse joints tending to hold it to a circular form, has no practical influence upon the collapsing pressure of a commercial lap.welded steel tube so long as this length is not less than about six times the diameter of the tube.
Page 719 - Rule. — Multiply the diameter of the driving pulley by its number of revolutions per minute, and divide the product by the diameter of the driven pulley.
Page 297 - An externally fired fire-tube or flue boiler is a steam boiler, part of the outer shell of which is exposed to fire or to the products of combustion, and containing flues through which such products pass from the furnace to the uptake.
