This paper traces the development of engineering technology from bifurcation to the present time. They assert that ET desires to be distinguished more than it seeks to be distinct. This analysis of the successes and failures of bifurcation lead to a differentiation between engineering technology's being distinct as a discipline and becoming distinguished in its own right. They offer some conjecture about the bright future of ET as a partner with science and engineering in an atmosphere of increased technological development but intense international competition.

Specimens of Delrin Acetal Resin with different stress-concentration factors were fatigue-tested in tension. Cyclic heat generation affects the strength of the part. Conventional stress-concentration factors may be used for Delrin, provided that the temperature is kept low enough, either through low loads or good heat transfer.
