basis of research
Is it possible to “on the fingers” explain how to drive, using the full 100% potential of tire adhesion to the road surface? Can!
To do this, we represent the forces acting on the car in turn with the help of the so-called “traction circle”, that is, the graphic circle of the clutch. To do this, draw a cross and circle it equally distant from the center. In fact, this is a graph of accelerations G in each phase of the turn: braking, moving along an arc and accelerating. Suppose that in all three phases of the tire has the same coefficient of friction, allowing you to develop lateral acceleration in 1.1G. If you exceed it, the tire will begin to slide, and this, as you know, slows down the car. In our graph, these are the points of intersection of the straight lines of the cross and the circle. The upper part of the vertical line is braking, the lower is acceleration. Continue reading
Rally-raid “Silk Road 2009”: Choosing the desert
From the spectacular picture it is difficult to imagine that the sand can be dangerous and cruel. But when mountains of small silicon particles reach the horizon, it becomes uneasy. It seems the desert divides people into friends and foes. Maxim Gomianin went to the Karakum to meet those whom the desert recognized as his own. Photos of the author, “Volkswagen” and KamAZ.
Hearing the stern: “Smoking is prohibited on the street,” colleagues hastily hide cigarettes in their pockets. Continue reading
Monte Carlo Rally
The new Toyota Yaris WRC already at the first stage demonstrated a competitive pace and exemplary reliability – both crews of the Toyota GAZOO Racing WRC were able to finish the Rally Monte Carlo in the most difficult and unpredictable conditions.
Rally Monte Carlo, traditionally opening the program of the World Cup, is not only one of the most prestigious, but also, perhaps, the most difficult race in the calendar. Narrow lanes, constantly changing weather conditions, the very specifics of the winter stage, when in some corners the riders drive on dry asphalt, and in others they can wait for insidious frost – all this makes pilots and navigators give 100% of their capabilities.
