Researchers have demonstrated new wearable technologies that both generate electricity from human movement and improve the comfort of the technology for the people wearing them. The work stems from an ...

Perhaps few physical concepts have received less attention relative to their importance than friction. Learning the 'effective' notions of static and sliding friction, students of mechanics can ...

If we zoom in on a cross section of rope to examine the forces acting on a small sliver, we can see how static friction is acting against T Load, which is equalizing the tension mismatch so that ...
