1 month agoThe squeal of peeling tape, explained
Micro-cracks in adhesive tape's adhesive layer generate weak shock waves that produce the screeching sound when tape is unspooled from its roll.
Tuning frictional behavior on the fly has been a long-standing engineering dream. This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.
the automation of heavy machinery enabled plants to operate continuously, increasing productivity and revenue. The downside was that any small hiccup was acutely felt, cascading through the production line. At first, it was assumed that inadequate lubrication of factory equipment was causing parts to seize up or break apart. And so, the Lubrication and Wear Group of the Institution of Mechanical Engineers, along with the Iron
Rimpact's Chain Damper was launched in 2024, and since then, interest in drivetrain feedback mitigation seems to be gaining momentum. The fact that current World Cup DH ruler Jackson Goldstone uses a similar device on his bike has likely caused quite a spike in interest. On their part, Rimpact supported 15 World Cup DH Teams through last season, and they're expecting that number to grow this year.
