PECULIARITIES OF DRY FRICTION
Some peculiarities of dry friction that represent the outcomes of several well-known physical phenomena but that are insufficiently accurately and simply explained in the scientific literature, are analyzed in this paper. The authors research into the reasons for the oscillation of strings of bowed string instruments in furtherance of the laws of mechanics; they also explain differences in the sound produced by strings of bowed and plucked instruments; they study the reasons for the motor car skid and provide their recommendations how to overcome it. The recommendation to rotate the steering wheel in the direction of skidding rather than vice versa as the one could expect from the viewpoint of common sense, gives rise to confusion and even protest of drivers (mainly, the new ones) and drastic consequences. Let us once again emphasize that this driving pattern refers to rear-wheel steering cars (so-called "classics"). As for frontwheel drive cars, one can turn the steering wheel in the opposite direction of the skid without retarding the throttle, but it is also advisable to release the brake of the front wheels and fulfill the braking by the rear wheels only.
