Century Dictionary and Cyclopedia
- Of or pertaining to the metacenter.
- In biology, pertaining to a new center around which new diverging modifications are produced.
- adj. Of or pertaining to a metacenter
- adj. genetics (of a chromosome) Having the centromere approximately in the middle, such that the two arms are of similar length
- n. A metacentric chromosome
- adj. having two equal arms because of the median position of the centromere
- adj. of or relating to the metacenter
“A V-shaped metacentric chromosome has two arms: 10 metacentric chromosomes would have a total of 20 arms.”
“The curve may be constructed in the following manner: Having found by calculation the position of the transverse metacenter, M, for a given displacement -- Figs. 1 and 2 -- the metacentric height, G M, is then determined either by calculations, or more correctly by experiment, by varying the position of weights of known magnitude, or by the stability indicator itself.”
“Having obtained the metacentric height, reference to a diagram will at once show the whole range of stability; and this being ascertained at each loading, the stowage of the cargo can be so adjusted as to avoid excessive stiffness in the one hand and dangerous tenderness on the other.”
“The scale having previously been properly graduated, the metacentric height for the draught and state of loading can be at once read off in inches, while as a check the water can be transferred from the one test tank to the other, and the metacentric height read off as before, but on the opposite side of the zero pointer.”
“The object of Mr. Alexander Taylor's indicator is to measure and show by simple inspection the metacentric height under every condition of loading, and therefore to make known the stability of the vessel.”
“Round the top of the scale, at D, are engraved four different draughts, and under these are the metacentric heights.”
“Similarly, if the center of gravity is lowered 6 in. on the same displacement, the curve, B, will be found, and in this manner comparative diagrams can be constructed giving at a glance the stability of a vessel for any given draught of water and metacentric height.”
“The metacentric height is found as follows: The ship being freed from bilge water, the roller scale is turned round to bring to the front the mark corresponding with the mean draught of the vessel at the time, and the zero pointer is placed opposite the surface of the liquid in the gauge.”
“Having obtained the curve, A, in this manner for a given metacentric height, we will suppose that on the next voyage, with the same displacement, it is found that, owing to some difference in stowage, the center of gravity is 6 in. higher than before.”
“If the centromere is in the middle, the chromosome is metacentric and the chromosome arms are equal in size.”
