Page 20 - Multiply the numerators together for a new numerator, and the denominators together for a new denominator.
Page 121 - Powers, are certain simple instruments, commonly employed for raising greater weights, or overcoming greater resistances, than could be effected by the natural strength without them. These are usually accounted six in number, viz. the Lever, the Wheel and Axle, the Pulley, the Inclined Plane, the Wedge, and the Screw.
Page 23 - The denominator of a decimal, though never expressed, is always the unit, 1, with as many ciphers annexed as there are figures in the decimal.
Page 21 - Rule. — Multiply the whole number by the denominator of the fraction, add the numerator to the product and place the denominator under the result.

Page 275 - ... way of employing the strength of horses. Robertson Buchanan states, that the mechanical effects of men in working a pump, in turning a winch, in ringing a bell, and rowing a boat, are as the numbers 100, 167, 227, and 248. According to Hatchette, of a man working at the cord of a pulley to raise the ram of a pile engine = 50 dynamical units.
Page 133 - The power is to the weight which is to be raised, as the distance between two threads of the screw, is to the circumference of a circle described by the power applied at the end of the lever.
Page 61 - In a right-angled triangle, the side opposite the right angle is called the Hypotenuse ; and the other two sides are called the Legs, and sometimes the Base and Perpendicular.
Page 109 - BRICKWORK is estimated at the rate of a brick and a half thick. So that if a wall be more or less than this standard thickness, it must be reduced to it, as follows : Multiply the superficial content of the wall by the number of half bricks in the thickness, and divide the product by 3. The...
Page 61 - The circumference of every circle is supposed to be divided into 360 equal parts, called degrees ; and each degree into 60 equal parts, called minutes ; and each minute into 60 equal parts, called seconds ; and these into thirds, &c.
