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 ...

Materials scientists are measuring the rolling friction of tiny, micrometer-sized particles. These measurements permit them to better understand everyday products such as concrete. For the first time, ...

The resistance of automotive tires to rolling eats up anywhere from 20% to 50% of the energy used by the car. So if auto and tire engineers could cut the rolling resistance in passenger-car tires by ...

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 ...

During commercial flat rolling of steel and aluminium strips control of the coefficient of friction at the roll/work piece contact is achieved by careful choice of the lubricant. The choice also ...
