First, second, third… Three racing car across the finish line three car team of the Soviet Union. Long-awaited success! So in 1975, ended in Minsk in the first stage of the Cup of friendship socialist countries.
Suddenly hit a thaw after a frost can cause a lot of trouble. On the sidewalks and the streets turned into a real ice rink, go is not easy, especially for the elderly. But ice is not terrible, if in advance to stock up on dry sand and a water-resistant glue such as “Phoenix”, “Point-1” Read more…
To permit sheet metal, need metal shears and a line with the Scriber for drawing cut lines. And if you can see the curved workpiece? Use the bolt or stud of suitable length, as shown in the figure, the nut will trace the edge, and the end of the stud resting in a scissors — Read more…
The fourteenth may 1905 in the Tsushima Strait in the last General naval battle of the Russo-Japanese war met 2nd Pacific squadron and the combined fleet of Japan In a six-hour battle killed four Russian battleship, and other ships were damaged, the Fate of the battle practically decided the evening of that fateful day and night torpedo attack and surrender of the remnants of the squadron in the morning just put the final point. On the Tsushima written many books and articles, however, one obvious fact is not noteworthy authors. The fact that the Japanese “line of battle”, strictly speaking, 2/3 were not “linear”- of the 12 units were part of the units and Kamimura, eight were armored cruisers. And these ships made a notable contribution to one of the most brilliant and decisive victories at sea in the XX century.
Even the person far from technicians, often have to Unscrew-screw the screws, bolts, nuts (hardware — so often referred to in abbreviated form these metal products) are designed for this tool — a wrench. Each key caused the size of its working parts, simply — throat. But the corresponding value is the size of the key — referred to in the technical handbooks by the letter S (the distance between the opposite parallel faces on a nut, bolt head or screw), is not listed on any of the fasteners. No, as a rule, these data and the attached to any technology operating instructions and repair even in the notation and in the drawings, although other information about fasteners in them abound: specify thread size, and her step sometimes the length and even the type of heat treatment, often tightening torque. But most of these data — structural, and they need to manufacture parts. When the adjustment, repair or Assembly work of the above settings thread, except the last one are not in demand. For a mechanic it is much more important to know what size front axle you need a key for the head of one or the other of the screw or bolt and nut (or, as professionals say, “the key is how much”).
Large problems sometimes arise because of the small details. Take, for example, the servo-mechanism, reduces the efforts on arms control such a powerful and popular tractors as Chelyabinsk Т100МЗ or T-130. They have the bushing hole (see figure), is pressed into the housing of the servo-mechanism, performs reciprocating movement of the pusher, the transmitting motion of the control lever rotate the spool getorcreatenode site. On the pushrod and is an ill-fated piece is a small rubber ring that provides a reliable seal between the follower and the walls of the sleeve.
The aircraft belongs to those fields of technology which are developing particularly rapidly. In a historically short period of time, speed, altitude, payload, flight range of the aircraft has increased several times.
In the literature on model airplanes is not so much focus on radio-controlled models of seaplanes, although, in practice, many enthusiasts prefer them purely “land”, considering the “waterfowl” more interesting for manufacturing and piloting. Many of them also refer to the usability of such models compared to those that are equipped with wheel chassis, because “land” is not everywhere possible to find a large enough area with asphalt or concrete path for takeoff and landing. While any aquadrome — a pond, lake or river to find not so difficult. In addition, experts argue that take-off and landing in the water are not in the example easier.
Instead of installing switches ship modelers often put on the deck bare conductors or put the bulky switches. Naturally, these alien items spoil the appearance of the model. At the station of young technicians of the city of Sochi for many years put on an improvised model of the microswitches (see figure), Tali. Then put the spring and install the bracket-holder. The deck clip is fastened with copper rivets. The switch is ready. Connecting the wires, you can test the reliability of his work.
