Dynamic analysis of helical spring systems explores the time-dependent behaviour of coil springs under oscillatory, impact and resonance conditions. Helical springs are fundamental elastic elements ...

Spring rate remains about linear (Hooke's Law) until gradual coil dampening and loss boost rate. Make free length a reference dimension so spring makers can adjust it as needed to obtain load at a ...

Crystals are usually imagined as rigid objects with flat faces and straight edges. A research team led by the University of ...

Researchers created helical porous organic crystals that reversibly stretch and contract as solvent molecules leave and ...

A torsion spring is a component made from elastic material that, when twisted, exerts a moment resisting the rotation. Common types of torsion spring include helical torsion springs, torsion bars, and ...

Up, down, to the left and to the right…. – the servo hydraulic testing machine HB 100 of Zwick in Ulm considers all possibilities and performs both tensile/compression and torsion tests on helical ...

Customized machined springs let designers integrate multiple features into one piece. The springs can be designed to address requirements for rate, reactions at desired deflections, combined rates, ...

Molecules that extend and contract under external stimuli are used to build molecular machines with nanomechanical functions. But although common in biological systems, such extension and contraction ...
