b) Design a single row deep groove ball bearing with basic dynamic load rating of 33 KN to be used in a turbine to carry a radial load of 1612 N. The expected life of the bearing is 5400 hours at 501 rpm. Take k=3 for all types of ball bearings. Take the value of the shock load factor as 1.8. The radial and axial load factors are 1.3 and 1.6 respectively and the rotational factor is 1. Calculate:
i) Expected life of bearings in millions of revolutions
ii) Design equivalent dynamic load in N
iii) Basic equivalent dynamic load in N
iv) Axial load acting on the bearing in N
