torque {slgf}

Locknut data on torque required to tighten a fixture by plating method

Description

Meek and Ozgur (1991) analyzes the torque required to strengthen a fixture (bolt or mandrel) as a function of the fixture's plating method (cadmium and wax, heat treating, and phosphate and oil, denoted CW, HT, and PO, respectively).

Usage

data(torque)

Format

A data frame with 60 rows and 3 variables:

Torque

the response, the torque required to tighten the fixture.

Fixture

the type of fixture, bolt or mandrel.

Plating

the plating treatment, CW, HT, or PO.
