For over a century, the world’s greatest minds could map the heavens, but not weigh the Earth. Newton’s theory had a missing number, and many believed it could never be found.

Design engineers routinely rely on bolted joints, yet most guidance focuses on axial stiffness—often overlooking moment (pitch) stiffness, which can dominate compliance in ...

Abstract: The method of analyzing the performance of vertical axis turbines using aerodynamic performance prediction models, such as multiple streamtube models and double-multiple streamtube models, ...
