When the resultant acts away from the shear centre axis, then the beam will not only bend but also twist.10. Bearing Preload . (495), n Zdk (495) The correlations between load and displacement, when only axial load is applied to bearing, is easy to analyze, because all rolling elements receive same amount of load. But, when the radial or com-bined load is applied, itss difficult because of var-ying load distribution. Axial displacement against axial load can be calculated as follows.calculations for efficiency of cement ball millcalculations for efficiency of cement ball mill.
