Westbrook 1962 General Electric structural materials price-vs-volume plot

The classic plot Tom uses to introduce the price/volume relationship in structural materials. Source: Jack Westbrook, internal GE memo, 1962. Notable as a corpus-recurring figure.

This is a summary of what I've been teaching, and they called it "Integration of Material Systems and Structures Development." Here's a plot from Jack Westbrook — Westbrook is a graduate of this department. He put this together in 1962 when he was at General Electric. So these are 1962 dollars. It was an internal memo at General Electric. It shows structural materials, dollars per pound, versus pounds per year that were used.
