Central European Time (CET): Austria, Belgium, Denmark, France, Germany, Hungary, Italy, Luxembourg, Netherlands, Norway, Poland, Sweden, Switzerland, Spain; Algeria, Israel, Libya, Nigeria, Tunisia, Zaire. Notches (such as grooves and holes) and changes in cross section (shoulders and offsets) as well as various clamping methods give rise to local stress concentrations σmax, which are usually far in excess of the nominal stresses: Change in resistance caused by change in temperature. Platinum wires –220 ... 850°C, Nickel wires –60 ... 250°C, Copper wires – 50 ... 150°C, Semiconductors –40 ... 180°C.

g = 9.81 m/s2 is generally acceptable in technical calculations. 1 kp is the force with which a mass of 1 kg exerts pressure on the surface beneath it at a place on the earth. With Section moduli and geometrical moments of inertia NL = "neutral axis" See Moments of inertia for mass moments of inertia. Z = p/υ = ρ · c. For air at 20 °C and 1013 hPa (760 torr) Z = 415 Ns/m3, for water at 10 °C Z = 1.44 · 106 Ns/m3 = 1.44 · 106 Pa · s/m. t For uniformly retarded rotary motion (ω2 is smaller than ω1) ist α is negative. Centrifugal force Sound absorption Loss of sound energy when reflected on peripheries, but also for the propagation in a medium.I Axial moment of inertia: the sum of the products of all cross-sectional elements by the squares of their distances from the neutral axis.

The angle of rotation ψ is the angle of twist in rad of a bar of length l (conversion: 1 rad 57.3°, see Units of angle). See Section moduli and geometrical moments of inertia for polar planar moments of inertia Ip. Thermal expansion of the liquid is visible in a narrow glass tube. Liquid: Pentane (– 200 ... 30°C). Alcohol (–100 ... 210°C), Toluene (–90 ... 100°C). Mercury (–38 ... 600°C), Gallium (...1000°C). Body thrown obliquely upward (neglecting air resistance). Angle of throw α; superposition of uniform rectilinear motion and free fallVibration reduction Vibration damping If damping can only be carried out between the machine and a quiescent point, the damping must be at a high level (cf. diagram). Octave band spectrum The sound levels are determined and represented in terms of octave bandwidth. Octave: frequency ranges with fundamental frequencies in a ratio of 1:2. Mean frequency of octave Recommended center frequencies: 31.5; 63; 125; 250; 500; 1000; 2000; 4000; The following table gives a survey of the most important physical quantities and their standardized symbols, and includes a selection of the legal units specified for these quantities. Additional legal units can be formed by adding prefixes (see SI units) For this reason, the column "other units" only gives the decimal multiples and submultiples of the Sl units which have their own names. Units which are not to be used are given in the last column together with their conversion formulas. Page numbers refer to conversion tables.

The results of flow measurements on two geometrically similar bodies of different sizes are comparable only if the Reynolds number is of equal magnitude in both cases (this is important in tests on models). are set ahead by 1 hour (from approximately April to September north of the equator and October to March south of the equator). Wave Spatial and temporal change of state of a continuum, which can be expressed as a unidirectional transfer of location of a certain state over a period of time. There are transversal waves (e.g. waves in rope and water) and longitudinal waves (e.g. sound waves in air).civil year = 365 (or 366) days = 8760 (8784) hours (for calculation of interest in banking, 1 year = 360 days), 1 solar year3) = 365.2422 mean solar days = 365 d 5 h 48 min 46 s, 1 sidereal year4) = 365.2564 mean solar days. 1) 2) 3) 4) The above equation for σk (Euler's formula) only applies to slender bars with the following slenderness ratios W Section modulus of a cross section: indicates, for the edge stress 1, the inner moment with which the cross section can resist an external bending load. at (techn. atmosphere) = 1 kp/cm2 = 0.980665 bar 1 bar 1 atm (physical atmosphere) = 1.01325 bar1) 1 mm w.g.
