Factors influencing the proportioning of machine elements: stresses, deformations, and failure criteria as applied to shafts, springs, belts, bearings, gears. Design of Elements is a required course ...

First-principles calculations, rooted in quantum mechanics and executed without recourse to empirical parameters, provide a robust framework for predicting the mechanical and thermodynamic properties ...

Close up we see pistons move up and down or side to side. Pendulums sway, the small parts of machinery move. Gears drive larger wheels. Gears within gears spin. Shafts turn some mechanism that is out ...

Bits, bytes and silicon transistors? Boy, you have it good -- back in 1953, state-of-the-art computers were made of gears, sprockets, chains and cams, and we trusted them to accurately wreck lives ...
