ceramicbearing: Ceramic Ball Bearing Rolling Contact Fatigue Test

In Auburngrads/SMRD.data: Statistical Methods For Reliability Data - Datasets

Description

McCool gives the results of a life test on rolling contact fatigue of ceramic ball bearings. Ten specimens were tested at each of 4 levels of stress.

Format

A data.frame with 69 rows and 5 variables:

[, 1]	kilocycles	Accumulated cycles at event (in thousands)	Numeric
[, 2]	mode	Failure mode observed at kilocycles	Categoric
[, 3]	event	Event observed at kilocycles (failure/right-censored/left-censored/interval-censored)	Categoric
[, 4]	count	Number of events observed at kilocycles	Numeric
[, 5]	kilonewtons	Applied stress (in thousands)	Numeric
