Universal machines

The data presented in Figure 19.7 were obtained on a Sonntag-Universal machine which flexes a beam in tension and compression. Whereas the acetal resin was subjected to stresses at 1800 cycles per minute at 75°F and at 100% RH, the nylons were cycled at only 1200 cycles per minute and had a moisture content of 2.5%. The polyethylene sample was also flexed at 1200 cycles per minute. Whilst the moisture content has not been found to be a significant factor it has been observed that the geometry of the test piece and, in particular, the presence of notches has a profound effect on the fatigue endurance limit. 

Sample preparation and measuring apparatus has been discussed and hence this section will deal with the principal item, the tensile machine, together with grips and extensometer. The tensile machine is in fact very often a universal machine in that, apart from tensile tests, it can also be used for flexural, compression, tear and adhesion tests. The basic elements of a tensile machine are shown diagrammatically in Figure 8.10.

The engines described are perfectly efficient, reliable and universal machines. As such, they allow the creation of basic or complementary energy sources. Their existance is neither purely theoretical nor in its early developmental stages. Rather, they have been extensively tested and are currently available.

The modern technology often requires that TSE performs a series of different functions. Owing to limitation of L/D, even these universal machines may profit from additional, external, either dispersive or distributive mixers. These devices are discussed in the following parts. 

The usual approach is to use a tensile" or universal testing machine that is equipped with a compression load cell. The compression takes place between parallel steel plates, which may incorporate a self-alignment mechanism. Rather than a universal machine, an apparatus working in compression only is equally satisfactory if the volume of work justifies a dedicated apparatus. An alternative is to use a compression cage in a tensile machine effectively to reverse the motion of the machine. However, these are now seldom seen, as they can introduce considerable friction errors, and there is always difficulty in alignment. As will be appreciated, for stiff materials the forces and hence machine capacity required can be large. 

Both the Doppler slice and the ion TOP measurement are essentially in the centre-of-mass system. Therefore the measurement directly maps out the desired 3D centre-of-mass distribution, i.e. d aj v dv dO = I 6,v) v in Cartesian velocity coordinates (d (r/diVx dvy dv ). Thus, the double differential cross-section I 6,v) is obtained by multiplying the measured density distribution in the centre-of-mass velocity space by and then transforming from the Cartesian to the polar coordinate system. This procedure has to be contrasted against the conventional neutral TOP technique (either in the universal machine or by the Rydberg-tagging method), for which the laboratory to centre-of-mass transformation must be performed, or against the 2D ionimaging technique, which involves 2D to 3D back transformation.

Type (a) has the disadvantage that the material falls from a great height, just as it does from a belt conveyor mounted under the ridge of the roof of a building. With a boom stacker of type (b) the height of fall can be keptdown to a minimum. Finally, type (c) is a universal machine, which is more particularly suitable where two...

Such finitary systems which have this maximal computational power are known as universal machines, or universal computation systems, sinee they can be programmed to perform any calculation that is possible on a finitary eomputation system. Thus, any computability question that would be true for one of them would be true for all of them. Therefore, when used without qualification, incomputability usually refers to something which is incomputable on a universal computation system. 

Tensile strength was determined according to ISO-37 with a universal machine, Zwick 1435. The same testing machine was also used for hysteresis and relaxations tests of the studied vulcanizates. Based on the results obtained from the hysteresis measurements, Mullins effect (defined as Em = ( Wi - Ws / Wi ) 100% ) was also calculated. Microstructure observations were carried out using scanning electron microscope (SEM).
