Page 190 - This horizontal shaft carries a collar, from which there project two small pins at diametrically opposite points. By sliding the shaft slightly to the right, the bevelled wheels are drawn out of gear, and the pins projecting from the collar put in position for actuating the testing arrangement. On the lid proper there are three orifices, one immediately in front of the test-light, and the other two at either side of it.
Page 18 - Maxwell denned the coefficient of viscosity as follows: "The coefficient of viscosity of a substance is measured by the tangential force on unit area of either of two horizontal planes at unit distance apart, one of which is fixed while the other moves with unit velocity, the space between being filled with the viscous substance.
Page 191 - During the heating of the oil the stirrers should be moved at short intervals by turning the handle b several times. The more rapidly the oil is heated the oftener the stirrers should be rotated. When nearing the point at which the oil is expected to flash, it is advisable to reduce the rate of heating in order that the observations may be more readily and accurately made. If necessary, a rough test may be performed first, to give some indication of the temperature at which the oil is likely to flash....
Page 28 - ... alteration of form is only produced by stresses exceeding a certain value, the substance is called a solid, however soft it may be. When the very smallest stress, if continued long enough, will cause a constantly increasing change of form, the body must be regarded as a viscous fluid, however hard it may be. Thus, a tallow candle is much softer than a stick of sealing-wax ; but if the candle and the stick of sealing-wax are laid horizontally between two supports, the sealingwax will in a few...
