For a single-row, deep-groove, ball bearing, dynamic load capacity is \( 5.59 \mathrm{kN} \) and static load rating is \( 2.5 \mathrm{kN} \). The bearing is subjected to an axial load of \( 625 \mathrm{~N} \) and a radial load of \( 1.25 \mathrm{kN} \). Determine the equivalent load and life of ball bearing if: (a) Inner race is rotating (b) Outer race is rotating.
