Σελίδα 70 - The breadth of the back or head of the wedge being three inches, and the length of either of its inclined sides 10 inches, required the power necessary to separate two substances with a force of 150 Ibs; As 10 : 1 1-2 :: 150 : 22 1-2 Ibs., Ans.
Σελίδα 37 - Divide trie square of the given diameter by 2, and extract tJie square root of the quotient. (Art. 581. Obs. 1.) 17. The diameter of a round table is 4 ft. ; what is the side of the greatest square table which can be made from it 1 631.
Σελίδα 62 - ... 007 2. By the cooling in the cylinder and pipes 016 3. By the friction of the piston and loss .... 125 4. By the force required to expel the steam through the passages 007 5.
Σελίδα 70 - Wlten two bodies are farced from one, another by means of a wedge, in a direction parallel to its back. RULE. As the length of the wedge is to half its back or head, so is the resistance to the power. EXAMPLE. The breadth of the back or head of the wedge being 3 inches, and the length of either of its inclined sides 10 inches, required the power necessary to separate two substances with a force of 150 Ibs.
Σελίδα 60 - He found, that an engine which indicated 50 horses power, when fully loaded, showed, after the load and the whole of the machinery was thrown off, 5 horses, or one-tenth of the whole power. 2nd. 190 feet of horizontal, and 80 feet of upright shafting, with 34 bearings, whose superficial area was 3300 square inches, together with 11 pair of spur and bevel wheels, varying from 2 feet to 9 feet in diameter, required a power equal to 7'65 horses.
Σελίδα 54 - Multiply the square of the diameter of the cylinder in inches by the velocity of the piston in feet per minute, and -divide the product by 6,000 ; the quotient is the number of nominal horses power.
Σελίδα 17 - To multiply a whole number by a fraction, or a fraction by a -whole number, RULE.
Σελίδα 33 - CONTENTS OF A PYRAMID. RULE. — Multiply the area of the base by | of the perpendicular height, whether it be a square, triangular, or circular pyramid.
Σελίδα 67 - ... one-fifth of the space. The products, therefore, arising from the multiplication of the respective weights and velocities are the same. EXAMPLE 2. — A weight of 1 ton is to be raised with a lever 8 feet in length, by a man who can exert, for a short time, a force of rather more than 4 cwt. : required at what part of the lever the fulcrum must be placed ? - , = 5 : that is, the weight is to the power as 4 cwt.
