If you want to know how to make a sneaker with better traction, just ask a snake. That's the theory driving new research by an expert who is studying snake skin to help engineers improve the design of ...

The phenomenon of friction, when studied on a nanoscale, is more complex than previously thought. When friction occurs, an object does not simply slide its surface over that of another, it also makes ...

Fundamentals of surface contact: surface topography, asperity contact, interfacial phenomena. Friction theories and wear mechanisms. Temperatures in sliding contacts. Hydrodynamic, hydrostatic, ...

A research team led by CU Boulder has designed a new kind of synthetic “skin” as slippery as the scales of a snake. The research, published recently in the American Chemical Society journal Applied ...

Delving into history books, we can learn that already thousands of years ago the Egyptians realized that lubricants like water and oil helped reduce the friction of sledges that moved the heavy stones ...

The essence of mechanical engineering is problem solving. MEs combine creativity, knowledge and analytical tools to complete the difficult task of shaping an idea into reality. Mechanical engineering ...

Surface roughness plays a critical role in mechanical engineering, especially in how parts interact under stress. A rough surface increases friction, which can be beneficial in applications like brake ...

Mechanical engineers work with materials from the nanoscale to airplanes and rockets. They are involved in creating and improving mechanical systems such as self-driving cars, aerial drones, the ...

Mechanical engineering is a broad discipline concerned with the design, analysis and optimisation of machines, structures and processes that convert energy into useful motion and work. At its core lie ...
