Page 16 - If three forces acting at a point are in equilibrium they can be represented in magnitude and direction by the three sides of a triangle taken in order.
Page 38 - ... elongation of not less than 20 per cent, in a length of 8 inches.
Page 17 - ... the sum of the moments of those forces which tend to turn the body in one direction about...
Page 197 - S = diameter of shaft in inches. d- = square of diameter of high-pressure cylinder in inches, or sum of squares of diameters when there are two or more high-pressure cylinders. D2 = square of diameter of low-pressure cylinder in inches, or sum of squares of diameters when there are two or more low-pressure cylinders. P = absolute pressure in Ibs. per square inch, ie boiler pressure plus 15 Ibs.
Page 172 - Since the hypocycloid becomes a straight line passing through the centre of the pitch circle when the diameter of the rolling circle is equal to the radius of the pitch circle, it follows that the flanks of wheel teeth may be made radial.
Page 311 - C = 60 when the plates are exposed to the impact of heat or flame, and steam in contact with the plates, and the stays fitted with nuts and washers, the latter being at least three times the diameter of the stay and two-thirds the thickness of the plate they cover.
Page 309 - W W = width of combustion box in inches. P = pitch of supporting bolts in inches. D = distance between the girders from centre to centre in inches. L = length of girder in feet. d = depth of girder in inches. T = thickness of girder in inches. C = 500 when the girder is fitted with one supporting bolt.
Page 311 - The constants for flat surfaces when they are supported by stays screwed into the plate and nutted, or when the stays are nutted in the steam space, 25 per cent. This is also applicable to the constants for flat surfaces stiffened by riveted washers or doubling strips, and supported by nutted stays.
Page 311 - C = 80 when the plates are exposed to the impact of heat or flame, with water in contact with the plates, and the stays screwed into the plates and fitted with nuts.
Page 17 - The moment of a force about any point is the product of the magnitude of the force and the perpendicular distance from the point to the line of action of the force.
