Imagine walking from one side of a swimming pool to the other. Each step takes great effort—that's what makes water aerobics such effective physical exercise. The resistance you feel is caused by ...

For 15 years, scientists have been baffled by the mysterious way water flows through the tiny passages of carbon nanotubes—pipes with walls that can be just one atom thick. The streams have confounded ...

Disney researchers make robot-human interactions safer with a new fluid based drive system. When building robots that interact closely with humans, it is important to make the arms as light as ...

Although robotic devices are used in everything from assembly lines to medicine, engineers have a hard time accounting for the friction that occurs when those robots grip objects – particularly in wet ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...

It is well known that friction between lubricated surfaces is a chief source of energy losses in fluid power systems. Now, help is on the way due to research taking place within the Engineering ...

Transmission fluid and hydraulic fluid both lubricate and protect mechanicals parts, but that doesn't mean they're the same.

• Excessive seal friction wastes energy, accelerates wear, and can lead to premature failure. • Too little friction makes a seal prone to leak. • Pressure-activated hydraulic seals minimize both ...

Water molecules flow near the honeycomb-patterned walls of a carbon nanotube. Interactions between the molecules and electrons in the walls can cause ‘quantum friction,’ researchers propose in a new ...

Imagine walking from one side of a swimming pool to the other. Each step takes great effort -- that's what makes water aerobics such effective physical exercise. Imagine walking from one side of a ...
