Learning to Handle the Big Guns Summary: During the Mercury, Gemini and Apollo programs, random vibration was also utilized, with significant success. The wxplained systems are shown to meet different, but equally important, goals in the design, evaluation and screening of electrical, electromechanical and purely mechanical systems. But when a pr Reliability has been a recognized performance factor for at least 50 years. The handbook is written for reliability managers and engineers and provides guidance in developing and implementing a sound reliability program for all types of products.

Describes the theory and practice of using thermal stresses to accelerate aging in electrical and mechanical components.

The reults sugges that significant cost savings can be realized without compromising reliability by abandoning the fundamentally flawed yet long held perception and belief that reliability is mainly temperature driven.
