Flexible shaft couplings transmit torque from one shaft to another, and redress misalignment between them. The trick is that flexible couplings must act Flexible shaft couplings transmit torque from ...

I was splitting wood one day a few years back, getting next winter’s firewood ready on my hydraulic splitter. It normally handled my ash and oak with ease, but I had a particularly gnarly piece of ...

Materials — When complicated geometry proves more trouble than it’s worth, the deceptively simple function of transmitting torque can be improved by even small changes in chemical makeup. The core ...
