Answer:
(b) Given the Weibull parameters of example 11-3, the factor by which the catalog rating must be increased if the reliability is to be increased from 0.9 to 0.99.
Equation 11-1: F*L^(1/3) = Constant
Weibull parameters of example 11-3: xo = 0.02 (theta-xo) = 4.439 b = 1.483
Explanation:
(a)The Catalog rating(C)
Bearing life:
Catalog rating:
From given equation bearing life equation,
we Dividing eqn (2) with (1)
The Catalog rating increased by factor of 1.26
(b) Reliability Increase from 0.9 to 0.99
Now calculating life adjustment factor for both value of reliability from Weibull parametres
Similarly
Now calculating bearing life for each value
Now using given ball bearing life equation and dividing each other similar to previous problem
Catalog rating increased by factor of 0.61
