The first journey to the kingdom of cars

Today, the world cannot be imagined without cars - everywhere we are surrounded by a variety of mechanisms, which cannot be dispensed with. Cars carry us, build houses, help prepare dinner - but what they just do! How are they arranged, where did they come from and where can be used? Two fairy -tale friends will help these questions - Robik and Magik. Together with them, readers will travel to the kingdom of cars, which was described by the outstanding scientist-mashinov, professor Alexander Filippovich Krainev. They also find out what friction is, how the conveyor and escalator work, what the mysterious words" inertia ", “torsion" and“ damper ”mean, how planes fly and why the submarine does not drown.
