“This project started with a simple question: why do basketball shoes squeak?” Adel Djellouli, a study co-author and materials scientist at Harvard’s School of Engineering and Applied Sciences (SEAS), ...

Basketball shoes on a gym floor, bicycle brakes in need of a tune-up, or the squeal of tires are everyday examples of squeaking sounds. Such sounds have long been attributed to stick-slip friction, or ...

Taking inspiration from Leonardo da Vinci’s studies of friction, the ‘sneaker squeak’ question cuts to a deep problem in physics.

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 ...

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 ...

If you want to know how to make a sneaker with better traction, just ask a snake. That's the theory driving the research of Hisham Abdel-Aal, PhD, an associate teaching professor from Drexel ...
