Strange trail remains for these sleds, rapidly descending from the mountain: the impression is that someone drove on one ski. And only bends on the side added short stroke of the second track. Unusual sports equipment, the construction of which is available to all lovers of breathtaking skiing the steepest slopes, has developed our reader from Magnitogorsk Sergei Chadin. Made of wood, the sleigh combines originality of design and ease of performance. For their manufacturing are required Board or thick plywood and a saw.
MIRACLE SLED
But not to throw out it! And involuntarily thought creeps in to make it a foldable frame. The same as, say, the “Kama”. I reviewed the literature on the subject (including the publication in “M-K” № 3, 1990) and left unsatisfied — too difficult was the recommended design. Had to develop my — more simple. Tried it and now offer to the readers.
A kite is considered to be the grandfather of modern aircraft. This harness motorless soaring leader was the first aircraft in the so long ago, when there was still such thing — aviation. Unfortunately, in the future, kites were replaced by more udachlivey fellow sky — models of gliders and planes.
High speed RC model with electric drive is very popular with modelers-but-wickow and veteran athletes. This to a large extent contribute concise external form guide-registerof prototype that simplifies the design, allows you to make models from a variety of materials and used in the manufacture of a variety of technological methods — depending on experience, availability of certain materials and finished components (engine, onboard equipment and batteries).
The search for new solutions before the next sports season has led our members to very unusual for present-day design. In a subclass of HH-0.2 is now dominated by specialized yacht model. Basically it is a catamaran with a rigid sail-wing or newfangled pyramidal sailing tooling used again in mnogotochechnykh. However and those and others are clearly expressed signs of directions of designing of sports projectiles that have little in common with real yachts. So we tried to go back to the models one-korpusniki, refitting their sailing rigging. The fact that the classical scheme of a cutter with mainsail and staysail in its simplest initially losing performance in connection with birth defects tractive effort of the sails. We have used the so-called stukeley scheme (often referred to as the L-shaped mast). It has much better properties, as it provides the most Agnolo element snap — grotto — optimally and in a wide range of settings of the sails. Do note that designs based on technically sophisticated “bells and whistles” (like rotary wing masts and the like) are generally not considered when creating the model students all that’s out.
From the family of microstructures developed by students of Kharkiv Institute of mechanization and electrification of agriculture, the easiest and most accessible for self-production – how “the Kid” (HIMESH-2): it is the most used units and components of machinery produced by industry. It’s a small two-wheeled machine driven reaching for her operator. A large set of interchangeable towed and mounted implements makes a compact and versatile, allows to use it for plowing, harrowing, cultivating, hilling and other operations soil cultivation, plant care, and in the coupling with a single axle truck – like vehicle for transportation of various household goods. In the latter case, the operator becomes the driver and is placed on suspension seat on the front of the truck. Thanks to these properties, the tillers can be applied not only in a personal farming, but also can be used for mechanization of labor-consuming processes in crop production, especially in vegetable production and experimental plots of breeding stations, as well as livestock and greenhouses.
A rural resident with a large garden and cattle, will love shredder, made by a craftsman from the village of Bornukovo Nizhny Novgorod region Yevgeny Kulikov. With its help in the harvest of apples years, processed fruit juices and wine, and daily life facilitated the process of preparation of feed for domestic animals in those places hold a lot.
Usually mention the proverbial fifth wheel. However, some automakers use a formula, reflected in the name of our material. They really believe the fourth wheel in the car superfluous. Judge for yourself: unlike a four-legged three-legged stool on an uneven base does not wobble (remember school: three points can be spend a plane, and thus only one). Therefore, trehalose frame will be more rigid and the car will be more lightweight and durable (and hence cheaper).
