From the properties of arcs of circles, if an arc has degree measure m and radius r, its length L is... 

To make the diagram easier to study, we have painted every second area between the ellipses black as seen in Fig. 4. From this we can see how the thickness of these areas, which represent the k value, varies over the diagram. The k value is constant along arcs of circles that pass through A and B. 

Providing there are no re-entrant curves or angles, any shape, including circles, can be cut out of sheet glass. Tangential scratches are made round curves, one at a rime and the waste glass broken off, circles and arcs of circles are best drawn with a diamond compass, which is illustrated in Fig. 6.5. 

The areas of curves in polar coordinates may be obtained in a similar manner. Divide the given surfaces up into slices by drawing radii vectores at an angle dO apart, and subdivide these slices by drawing arcs of circles with origin as centre. Consider any little... 

The sample workpiece has a drill hole for the bearing with a roundness tolerance of 0.01 mm (Fig. 1). Roundness tolerances can also be used for arcs of circles with less than 360 coverage [SCHMIO]. 

In the pigment circle (Fig. 22), a number of pigments are listed. The pigment colours do not correspond to pure colours, but lie between them. If two pigments that are not complementary are mixed, the colour produced will lie between them, on the shorter arc of circle... 

Both longitudinal (linear axial crack) and circumferential (arc of circle crack) breaks were simulated. 

Fig. 25.2. Typical plots obtained for the main models and realistic examples, (a) Frequency dispersion of e and adsorption e" for a pure Debye model on (b) the corresponding Cole-Cole plot (e" vs. s ), (c) Cole-Cole plot commonly encountered with a real dielectric solid showing an arc of circle centred out of the e abscissa and (d) with conduction loss, (e) Charge hopping model diagrammatic representation of the potential well and corresponding plots of ct(co) vs. logo) and e" vs. e for non-interacting free charges (f) similar plots for system with trapped charges examples of a" vs. a and Z" vs. Z plots are also given. Note the relation between the slope of a(m) and the depression of the semicircle in the a" vs. a plane also note that co increases in opposite directions in the e" vs. e and a" vs. a plots ...

To this end, I traced, on three paper sheets, three shapes representing the bases of three formed systems, each of two portions of film spheres and a partition. I understand by the base of such a system the whole of the arcs of circles along which it is based on the surface of the liquid, neglecting the small annular masses. Here is one method by which I plotted the drawings in question ... 

In an article in response to this Note, I have shown that the method employed by Mr. Hagen, although clever, could give only a value more or less far away from true, because the meridian arcs of the bulges and narrowings are not arcs of circles, and that in substituting for the latter of the arcs of a sinusoid, obviously closer to those of the real curve, one obtains a notably different result.
