The less work required to translate an object, the better. Avoiding sliding friction — a major sinkhole of applied force for motion — is accomplished through rolling. A: Ironically, with increased ...

Ball splines are sometimes misunderstood in the intricate landscape of high-precision engineering. For one, they can be mischaracterized as fragile, or ill-suited for heavy loads. But these innovative ...
