17 de jun. de 2008 · Az MP3 tud tárolni 3 féle hangot/jelet: 1,2,3. Viszont az a baj, hogy a CD-n 5 féle hang van: 1; 2; 2,4; 2,8; 3. Mivel a 2,4-et nem tudja az MP3 tárolni, így azt 2-nek fogja értelmezni, a 2,8-az pedig 3-nak. Így persze nem ugyanazt kapod, mint ami a CD-n van, viszont átlagember átlagfüllel (átlag MP3 lejátszóval) nem hallja meg.
Tensile testing is most often carried out at a material testing laboratory. The ASTM D638 is among the most common tensile testing protocols. The ASTM D638 measures plastics tensile properties including ultimate tensile strength, yield strength, elongation and Poisson's ratio.

The test consists . and the gage length of reduced section should be at least four times the diameter . and Materials standard ASTM E8 or other standards organizations, like the . What is a tensile test?In the field of materials science and engineering, a tensile test is a widely used method to determine the mechanical properties of a material, specifically its response to tensile forces. It involves subjecting a specimen to an ever-increasing tensile load until it reaches its breaking point. By measuring the applied force and the resulting deformation . From each, we can find the appropriate tensile-bar shape for testing of sheetmetal products. ISO takes the approach of designating Type I, II and III bars, which represent ASTM, DIN and JIS shapes, respectively. These tensile-bar shapes exhibit significant differences in width and gauge length (Table—Differences in Tensile Bars and Fig. 2). The 50 kN capacity and the fully variable test speed of 0.2 to 51 mm/min make it possible to perform not only the CBR and Marshall tests, but many other applications as for instance Indirect Tensile test, Quick Triaxial tests, Unconfined and Uniaxial soil testing and, in general, all test to be performed under displacement control.
The tensile test on tubes and tube sections is performed according to ISO 6892. The test is used to determine characteristic values such as tensile strength, . Tube strip specimens (or tube section specimens) have a curvature on the inner and outer surface and in practice are usually clamped with flat jaw inserts. However, it should be noted .Tensile testing also provides tensile strength (at yield and at break), tensile modulus, tensile strain, elongation, . In the reduced section, a gauge length is defined, from which measurements are made to determine ductility (Fig. 21.1). Figure 21.1. Tensile test specimen.

Tensile testing characterizes the forming and structural behavior of sheet metals. The test involves loading a sample with a well-defined shape along the axis in tension, generally to fracture, and recording the resultant load and displacement to . The uniaxial tensile test is the most commonly-used mechanical testing procedure. However, while it is simple in principle, there are several practical challenges, as well as a number of points to be noted when examining outcomes. . The grips lie outside of this section, where the sample has a larger sectional area, so that stresses are lower .Both the load (stress) and the test piece extension (strain) are measured and from this data an engineering stress/strain curve is constructed, Fig.3.From this curve we can determine: a) the tensile strength, also known as the ultimate tensile strength, the load at failure divided by the original cross sectional area where the ultimate tensile strength (U.T.S.), σ max = P max /A 0, . Miniaturized Tensile Test (MTT) is one of the most widely used methods of SSTT . In the 1990s, a bow tie shaped specimen with V-shaped ends (Fig. 5 (a)), of which the reduced section is approximately 3 × 0.2 × 0.2 mm 3 with a slight tamper was proposed by LaVan et al. [58, 59]. This bow tie shaped specimen was primarily designed to overcome .

Ultimate Tensile Stress (UTS) and Ductility. It may be noted at this point that it is common during tensile testing to identify a “strength”, in the form of an “ultimate tensile stress” (UTS).This is usually taken to be the peak on the nominal stress v. nominal strain plot, which corresponds to the onset of necking.Tensile Specimen: Regardless of the thickness of the test coupon for qualifying the PQR, two number of tensile specimen are mandatory to be tested.Tensile test coupon welding specimen shall be drawn as per QW151, Reduced Section Tensile test specimen for Plate & Pipe : Specimen taken for testing shall be full thickness specimen when T ≤ 25mm.
5.1 Testing Machines—Machines used for tension testing shall conform to the requirements of Practices E 4. The forces used in determining tensile strength and yield strength shall be . a reduced section (for example, full cross sectional area specimens of wire, rod, or bar), the extensometer gage length .
