These days, it’s common among us hackers to load a stepper motor with forces in-line with their shaft–especially when we couple them to leadscrews or worm gears. Unfortunately, steppers aren’t really ...

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

Bolt it in place, and off you go: A slewing ring is a contained system of balls or rollers, caging, raceways, mounting provisions, and often, integral gearing as well. These large units are designed ...

Surface conductors containing external water-expandable elastomeric elements increase conductor bearing capacity in deep and ultradeep waters where water-saturated soils may lead to wellhead sinking, ...
