definition

A plan, drawing, sketch or outline to show how something works, or show the relationships between the parts of a whole.

example

Electrical diagrams show device interconnections.

definition

A graph or chart.

definition

A functor from an index category to another category. The objects and morphisms of the index category need not have any internal substance, but rather merely outline the connective structure of at least some part of the diagram's codomain. If the index category is J and the codomain is C, then the diagram is said to be "of type J in C".

definition

To represent or indicate something using a diagram.

definition

To schedule the operations of a locomotive or train according to a diagram.

Indicator diagram corresponding to 1 lb.

The lines of constant energy on the diagram are called Isenergics.

The pull recorded on the diagram includes the resistances due to acceleration and to the gradient on which the train is moving.

There should be a diagram for each step.

The indicated horse-power developed by a cylinder may always be ascertained from an indicator diagram and observations of the speed.

Lines representing efficiency ratios of o 6, 0.5 and 0.4 are plotted on the diagram, so that the efficiency ratios corresponding to the various experiments plotted may be readily read off.

The subjoined diagram will indicate the relationship of the forms.

The phenomena may be investigated by following a horizontal line across the diagram.

To the left of the diagram is shown (by firm lines) a system of canals laid out scientifically, and of drains (by dotted lines) flowing between them.

A diagram of a vapour compression machine is shown in fig.

The tree diagram is beginning to look rather complicated.

There is also a useful diagram showing how bacteria cause peptic ulcers.

If this carbon is all present as graphite, so that in cooling the graphite-austenite diagram has been followed strictly (§ 26), the constitution is extremely simple; clearly the mass consists first of a metallic matrix, the carbonless iron itself with whatever silicon, manganese, phosphorus and sulphur happen to be present, in short an impure ferrite, encased in which as a wholly distinct foreign body is the graphite.

Above the diagram are given the names of the different classes of cast iron to which different stages in the change from graphite to cementite correspond, and above these the names of kinds of steel or cast iron to which at the corresponding stages the constitution of the matrix corresponds, while below the diagram are given the properties of the cast iron as a whole corresponding to these stages, and still lower the purposes for which these stages fit the cast iron, first because of its strength and shock-resisting power, and second because of its hardness.

Whether your project is a quick family tree diagram with your kids for school or an ongoing, research-intensive genealogical search, the benefits frequently outweigh the time involved.

Trenton is served by the Pennsylvania (main line and Belvidere division) and the Philadelphia & Reading railway systems, by inter-urban electric railways, and by small freight and passenger steamers on the Delaware river; the Delaware && Raritan Canal connects with r 0 U Argent Diagram of Half of Trente et Quarante Table.

To obtain an open diagram of these movements the plate must be moved, say by clockwork.

For obtaining an open diagram of an earthquake the best type of apparatus consists of a pair of horizontal pendulums writing their movements upon a moving surface.

In the diagram there is indicated the situation of the cortical centres for movement of the vocal cords.

The magnifying power of the telescope is = Ff /ex, where F and f are respectively the focal lengths of the large and the small mirror, e the focal length of the eye-piece, and x the distance between the principal foci of the two mirrors (=Ff in the diagram) when the instrument is in adjustment for viewing distant objects.

It was then discharged through the regenerator, depositing heat for the next charge of air in turn to take up. The indicator diagram approximated to a form made up of two isothermal lines and two lines of constant pressure.

This diagram consists of a polygon whose successive sides represent /\p9

The relations will be understood from the annexed diagram, where corresponding lines in the force-diagram FIG.

As regards the funicular diagram, let LM be the line on which the pairs of corresponding sides of the two polygons meet, and through it draw any two planes w, w.

Thus ii AB, BC, CD represent the given loads, in the force-diagram, we construct the sides corresponding to OA, OB, OC, OD in the funicular; we then draw the closing line of the funicular polygon, and a parallel OE to it in the force diagram.

It may be noticed that if we take an arbitrary pole in the force-diagram, and draw a corresponding funicular in the skeleton diagram which represents the frame together with the lines of action of the extraneous forces, we obtain two complete reciprocal figures, in Maxwells sense.

To find the pressure exerted by a bar AB on the pin A we compound with the force in AB given by the diagram a force equal to P. Conversely, to find the pressure of the pin A on the bar AB we must compound with the force given by the diagram a force equal and opposite to P. This question arises in practice in the theory of three-jointed structures; for the purpose in hand such a structure is sufficiently represented by two bars AB, BC. The right-hand figure represents a portion of the force-diagram; in particular ZX represents the pressure of AB on B

Hence set out the possible direction of Bs motion in the velocity diagram, namely cbi, at right angles to CB.

Hence draw a line through O in the velocity diagram at right angles to AB to cut cbi in b.

It will be understood that there is a new velocity diagram for every new configuration of the mechanism, and that in each new diagram the image of the rod will be different in scale.

Following the method indicated above for a kinematic chain in general, there will be obtained a velocity diagram similar to that of fig.

The particular drought shown on the diagram is the result of an exceptionally early deficiency of rainfall which, in conjunction with the variation of demand shown by the dotted line b b, is the most trying condition.

The whole diagram shows, by the greater gradient of the unbroken straight lines, the greater demand which can be satisfied by the enlargement of the reservoir to the extent necessary to equalize the flow of the two driest consecutive years.

The line a" a" drawn from zero parallel to the first line, produced to the boundaries of the diagram, will cut the vertical at the end of the first year at the percentage of the driest year's flow which may be safely drawn continuously from the reservoir throughout the two years.

Similarly, the yield from any given reservoir, or the capacity required for any yield, corresponding with any mean rainfall from 30 to 100 in., and with the flow over any period, from the driest year to the six or more consecutive driest years, may be determined from the diagram.

If, therefore, the centre of that became so far removed to the right as to make j coincident with b, the diagram of stresses would become the triangle j'l'c', and the vertical pressure at the inner face would be nil.

This will evidently happen when the centre of pressure i' is two-thirds from the inner toe b and one-third from the outer toe c'; and if we displace the centre of pressure still further to the right, the condition that the centre of figure of the diagram shall be vertically under that centre of pressure can only be fulfilled by allowing the point j to cross the base to j" thus giving a negative pressure or tension at the inner toe.

Tensile stresses (indicated by broken lines on the diagram) are shown at the upstream toe notwithstanding that the line of resistance is well within the middle third of the section.

On examining the diagram it will be observed that the maximum compressive stresses are parallel to and near to the down stream face of the section, which values are approximately equal to the maximum value of the vertical stress determined by the law of uniformly varying stress divided by the cosine squared of the angle between the vertical and the resultant.

In the actual instrument, the paper diagram is mounted upon a drum caused by clockwork to revolve uniformly, and is ruled with vertical hour lines, and horizontal quantity lines representing gallons per hour.

Having arrived at the end of the district he retraces his steps, reopens the whole of the stop-cocks, removes the meter diagram, takes it to the night complaint office, and enters in the " night inspection book " the records he has made.

The next morning the diagram and the " night inspection book " are in the hands of the day inspector, who compares them.

He finds, for example, from the diagram that the initial leakage of 2000 gallons an hour has in the course of a 41 hours' night inspection fallen to 400 gallons an hour, and that the 1600 gallons an hour is accounted for by Distribution The earliest water supplies in Great Britain were generally distributed at low pressure by wooden pipes or stone or brick conduits.

Each of these drops is located by the time and place records in the book and the time records on the diagram as belonging to a particular service pipe; so that out of possibly 300 premises the bulk of the leakage has been localized in or just outside fifteen.

That described requires a diagram revolving once in a few hours, otherwise the time scale will be too close; but the ordinary diagram revolving once in 24 hours is often used quite effectively in night inspections by only closing those stop-cocks which are actually passing water.

Similar examinations by means of the stop-valves on the mains are also made, and it often happens that the residual leakage (400 gallons an hour in the last case) recorded on the diagram, but not shut off by the house stop - cocks, is mentioned by the inspector as an " outside waste," and localized as having been heard at a stop-cock and traced by sounding the pavement to a particular position under a particular street.

Using the symbols of the diagram, it can be shown that the effect of placing the weight W at E instead of F is to cause the end of the beam to descend, as if under the action of an additional weight, w, at F such that w Wa(ml - l +tan 0)/h.

Behind the pulley at the top of the machine and on the same shaft is a spur wheel, which drives both of the spur wheels shown in the diagram.

The ratchet wheel is acted upon by a pawl which is shown on the diagram.

Next, a pair of mesenteries, marked II,II in the diagram, is developed in the sulcular chamber, its musclebanners facing the same way as those of I, I.
