The complexity of the modern theory of EHL provides an opportunity to seek simpler solutions. In previous research it has found that the classical equation of Reynolds "make difference" between rolling friction and sliding friction and for these two cases and their combination are obtained ...
He suggested a closed-form correlation to predict the overall drag coefficient on the vehicle as a function of the jet thrust coefficient according to accessible measurements (Finley, 1966; Warren, 1960). A new parameter was introduced by Stalder and Inouye (1956) to specify the jet strength,...
1.The conclusions indicate that the stability factors from Residual Thrust Method are larger than those from Janbu Method, and that the influence of water level on stability factor is a little greater than that from earthquake when Residual Thrust Method is used to calculat.从剩余推力法和简布法...
Hence the thrust (T) can be assumed to be proportional to ρ, D, Va, n, μ and (p0 − e): T∝ρaDbVacndμf(p0−e)g Since the above equation must be dimensionally correct it follows that MLT−2=(ML−3)aLb(LT−1)c(T−1)d×(ML−1T−1)f(ML−1T−2)g and...
An analytical equation based on the parameters that were being investigated was created to calculate the COF of each material. Different methods of partitioning weight were employed for the expected COF to assess the relative importance (RI) and individual feature's relevance. A Shapley decision ...
Summary of Test Method4.1 This test method is intended to provide a means ofdetermining the coefficient of linear thermal expansion ofplastics which are not distorted or indented by the thrust of thedilatometer on the specimen. For materials that indent, see 8.4.The specime 12、n is placed at...
5.9.2 Annular thrust bearing damping characteristics Examples of how damping coefficients vary with bearing parameters is given here for the bearing design considered in Section 5.7.4. Damping coefficient increases with oil viscosity and bearing area but decreases with gap and rotational speed. For the...
For tank discharges the energy balance equation is applied across a plane 0, inside the tank at stagnant conditions (that is, far enough away from the orifice that the velocity inside the tank is negligible) to a plane 2 where the discharge has expanded to the back-pressure, Pb. Except ...
1). Especially, at shallow depths, very high horizontal stresses occur, particularly in rocks affected by thrust faulting, whereas for depths ζ >1000m, the ratio of geostatic stresses Κ = σΗ /σν tends to that given by the classical elasticity (Eq. 2). The high horizontal stresses ca...
which can be performed automatically with the aid of a timing unit and/or can be performed manually, the last ray segment 4 of the arriving pulse or modulated radiation, after passing through the outlet opening 5d, strikes the calibration standard 9, which is thrust in front of the detector...
