Several factors can influence the driving range of a modern EV. For instance, larger wheels may look cool and all, but the wheel size can definitely affect EV range. Meanwhile, the ambient temperature ...

ETH Zurich Materials Scientists are the first to measure the microscopic forces involved when particles in suspensions such as concrete or paint roll past each other. Previously, such measurements ...

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 ...

Compressive forces (labeled F and F/2) keep the three inner rings in contact with the driveshaft. The ability to produce smooth, precise, and accurate linear motion is key to many manufacturing and ...
