The Soviet-Finnish war began on 30 November 1939 and ended on 12 March 1940. All this time our units had to overcome the fortifications of the “Mannerheim line”, created on the Karelian isthmus. This “line” became the most significant fighting. Rasstalas front is 135 km, it had a depth of defense around 95 km, and the Main defense line consisted of strong points, just within which it was built 800 wooden-earthen fire facilities Bunkers and 280 long-term firing installations (Pillboxes). All of them, as well as the other positions were covered by the first anti-personnel obstacles of the dozens of rows of barbed wire on concrete base. They were followed by anti-tank obstacles, saturated ditches and scarps. Space between them in huge quantities were made nadybali in several bands. Tanks could not pass, and the Marines had to overcome many roadblocks often three or four layer fire to undermine them. Such a difficult task sometimes allowed T-28 tanks, fire their 76.2 mm guns destroying dragon’s teeth. They could also deal with small Bunkers.

The fuselage of modern rezinomotornaya model aircraft usually consists of two parts: the power (it houses the rubber motor, is attached to the lug screw, wing) and the tail boom carrying the tail surfaces.

Modern modeling is different from the former, purely sports – this will not argue. The vast majority of adherents of the above-mentioned Hobbies is building models, not related to the competition. First, as it is abroad, a similar situation now exists in Russia.
Many accidents occur due to technical reasons, including due to faults of the brake system of the vehicle. One of the indicators of the effectiveness of this system is the braking distance, which for different categories of vehicles is regulated by state standard. Determined he may be on a special stand.
Remember how in one of the Russian folk tales bear arc bent? Took two legs of the barrel at both ends and through the knee. For while it attempts, as we know, was not successful, note that to perform this operation, in modern technical language, it took him three working “element”: one rounding (knee) and two power (paws). The most modern devices for bending tubes and bars contain the same three elements. Usually they are mounted on a special table. There is a metal loop, which is inserted into one end of the pipe, a stationary roller — on it is bent, and the movable roller with the lever.
Runabout created in 1957, little known at the time to a wide audience by engineer Alec Issigonis of the British Motor Corporation, justly called a masterpiece of design and autocostruzione. The urgent need for such a vehicle began to be felt in the large cities of great Britain in the mid 1950s due to increased car ownership and lack of space for Parking. That’s why an inexpensive, compact and economical car, capable to drive and Park there, where there is no place for a full-size, could find demand among buyers.
