Page 212 - Knots H, K and M are easily untied after being under strain. The knot M is useful when the rope passes through an eye and is held by the knot, as it will not slip and is easily untied after being strained.
Page 183 - DrillinK templates are in multiples of four, so that fittings may be made to face in any quarter, and bolt holes straddle the center line.
Page 212 - stevedore" knot (M), (N) is used to hold the end of a rope from passing through a hole. When the rope is strained the knot draws up tight, but it can be easily untied when the strain is removed. If a knot or hitch of any kind is tied in a rope, its failure under stress is sure to occur at that place. Each fiber in the straight part of the rope takes...

Page 5 - ... described in the paragraphs following are, in general, the ones employed at the National Bureau of Standards in testing hydrometers, and it will be helpful to follow them to such extent as the need for accuracy requires. 7.2 In order that readings shall be uniform and reproducible, the hydrometer must be clean, dry, and at the temperature of the liquid before immersing to take a reading. It is particularly important that the stem be clean so that the liquid will rise uniformly around the stem...
Page 7 - ... tensions, and since surface tension is a specific property of liquids, it is necessary to specify the liquid for which a hydrometer is intended. Although hydrometers of equivalent dimensions may be compared, without error, in a liquid differing in surface tension from the specified liquid, the results of comparisons of dissimilar instruments in such a liquid must be corrected for the effect of the surface tension. 7.3.2 In many liquids spontaneous changes in surface tension occur due to the formation...
