tensile: Tensile breaking strength of steel samples

Description Format References Examples

Description

The breaking strength of samples of steel that were stress tested. This data set is called break in Nelson, Coffin and Copeland (2003). We changed the name because break is a reserved word in R.

Format

A data frame with 18 observations on the following variable.

bstrength

breaking strength (unknown units)
