Arched design with all other conditions being equal, will always be stronger, safer and cheaper structures of other types — especially when the arc itself consists of rods, working only on tension and compression. At the time, it was appreciated by the famous mechanic Kulibin, who created a scale model of the arch bridge, which was supposed to connect the banks of the Neva. The original arch design, suitable for the creation of greenhouses, conservatories, sheds, garages and other structures, have managed to create a reader of our magazine from Novgorod S. Y. Makurin. The module of such a set represents a Central design consisting of 240 wooden rods (rails) with cross-section 20×50 mm and a length of from 0.5 to 1 meter (volume of the material is 0.2 cubic meters). The module area is 15 square meters. Docking these modules, you can get the arch structures of any size and different configuration.
ARCH TO ARC – READY GREENHOUSE
Favorite car in the village is undoubtedly the all-wheel drive, all-terrain VAZ 2121 “Niva”. Trailers specifically for this model, having a large capacity and the ability to operate in off-road conditions, our industry, unfortunately, not released. What a pity! Need them villager is huge: it is necessary and the materials to bring, and fertilizer, and to deliver to the market the products of his garden. In short, the trailer to “the Field” is a must! That’s why I designed and built it yourself.
No, the headline is not a hoax. And not even the “joint work of members Kota, led by a talented teacher and organizer of technical creativity of rural children”. It is a workable mini-tractor is really created (and after extensive field testing has sent explanatory material about their design in the journal “modelist-Konstruktor”) 16-year-old Sretensky guy — Andrey Bobkov.
Now an extremely acute problem of processing individual land plots. The horse would plough the field! But where are these loshadke? Motor-block to replace? Well, if you believe the advertising avenues, such a solution seems quite reasonable. But in fact, alas, it turns out that not all can praise MB. Not to be unfounded, I will refer to the neighbors of tests of MTZ-0.5 plowing. So: we have a heavy soil (clay mostly). They advertised this walk-behind… takes 5-7 cm in depth. And this is with the suspended cargo, and special plough-wheels. Crop after such “processing” of the soil, as they say, never gonna happen.
In the journal “modelist-Konstruktor” already repeatedly told about motalbezadeh — tillage interesting mechanisms for gaining lately more and more popularity among Amateur designers. Indeed, the advantages of this wonderful device is undeniable. The fact that the winch (by the way, one of the most ancient mechanisms in the history of civilization), in contrast to the self-propelled tilling machines, sends its power to the creation of the pulling effort.
We offer cordovano-pilotando design developed in the model aircraft kraine Industrial syut Perm city under the leadership of K. Minkova. It is designed for engine KMD-2,5 and has a detachable wing, stabilizer and fin, which greatly simplifies the transport of the model and its repair. “Pilotage” is designed for those who have sufficient experience in modeling and wants to possess elegant and functional sports equipment.
Aware that in the modern mass automodelisme in a very objective and not very reasons there is a critical situation to the attention of athletes, club Directors, and especially the workers of the Federation of auto modeling sport of Russia unusual material. It is dedicated to the development of a new concept (hopefully, very promising!) class car — unmanaged vetrogonov.
This car, dubbed “Lyuga-750”, I designed and built quite independently, and this helped me a lot in the journal “modelist-Konstruktor”. The process of creating a car lasted about two years, and for several years operated it quite successfully. Of course, the first trip revealed a lot of shortcomings, but they are quickly eliminated, and the machine was updated and improved. Not long ago, the car passed state tests and technical inspection and was found fit for use.
