Recent experiments with tethered hawkmoths, and with large-scale mechanical flapping models, have successfully replicated some of the force-generating abilities of insects 3,4,5,6,7. Leading-edge ...

Fidget toys all have a satisfying mechanical action to engage with, and [uhltimate]’s OTF (out the front) “fidget knife” model provides that in spades. The model snaps open and closed thanks to a ...

Introduction The mode clamping mechanism is the most important part of forming section for the plastic injection molding machine. If this mechanism has double-toggle effects at the close position, it ...
