Description
From Cleveland (1993): data from an industrial experiment in which thirty rubber specimens were rubbed by an abrasive material. Measurements of three variables - abrasion loss, hardness, and tensile strength - were made for each specimen. Abrasion loss is the amount of material abraded from a specimen per unit of energy expended in the rubbing; tensile strength is the force per unit of cross-sectional area required to break a specimen; and hardness is the rebound height of a steel indenter dropped onto a specimen. The goal is to determine the dependence of abrasion loss on tensile strength and hardness
