However,the non-linear relationship between the bending moment and the sizes brings troubles in choosing an electric ma-chine of the CNC pipe-bending device. Therefore, this paper presents a formula to calculate the pipe-bending mo-ment, for improving the calculating efficiency and reducing the ...

Einstein had made a mistake in his calculations and corrected the prediction of 0.85" to twice that value, to 1.7". This correction came at the right moment, for in 1919 a British team, led by Arthur Eddington, set out to test Einstein's prediction of thebending of lightby the Sun. Th...
is such that the bending inertia of the female element in the plane of said minimum diameter is at least equal to the product of a bending inertia I, of the regular portion of the pipe on which the male tubular element is formed and a fraction f of the bending moment to be transferred...
ϕj is the rotational angle of the jth rolling ball at t moment, which can be expressed as (17)φj=2π(j−1)Nb+ωc·t+φ0ωc=(1−DbDp)·ωs2,where Nb is the number of rolling elements, and ϕ0 is the previous cage position. ωc and ωs represent the cage and the ...
When the moment of inertia caused by shear deformation is introduced into the infinitesimal section of the cable, the equilibrium state is shown in Figure 1. Figure 1 Open in figure viewerPowerPoint Cable balance diagram. According to Figure 1, the equilibrium equation of the infinitesimal section...
