Question:-
A ball-bearing is characterized by basic static capacity = 11000 N and dynamic capacity = 18000 N. This bearing is subjected to equivalent static load = 5500 N. The bearing loading ratio and life in million revolutions respectively are
Option (A)
3.27 and 52.0
Option (B)
3.27 and 35.0
Option(C)
2.00 and 10.1
Option(D)
1.60 and 4.1
Correct Option:
(B)
Question Solution:
Loading ratio = (C/P) = (18000/5500) = 3.27
Life (million revolutions)
= (C/P)3 = (18000/5500)3 = 35
