On the pages of popular French children’s magazine “Wife Anne” describes the two models of hang gliders, designed by Jean-Paul Movie and Christian Neuville. Wing Delta is an isosceles triangle with a height equal to half the base. The keel has the shape of a triangle with angles 90, 60 and 30°. Like most kites, wing “Delta” consists of a stitched frame and twine, wound on motoviltse. The cording is made of fine and durable matter, frame — wooden slats. The glider is very light, so to run it, a small gust of wind.SNAKES HANG GLIDERS

In Amateur practice it is often necessary to assemble temporary circuits and soldering details “stuck” (as a welder). While in one hand the wizard tweezers, soldering iron in the other; item, to which it is necessary to solder the other element or conductor, “spinning” on the table: — need a “third hand”. Proposals on this subject abound in scientific and popular technical journals. For example, in the form of two clamps mounted on a tripod, or gum, and then just a small grip.
In 1959, the USSR Ministry of communications has ordered the design Bureau of the famous Builder of helicopters N. I. Kamov unusual for this size car — a snowmobile. Developers were tasked to create a vehicle that could provide postal services in remote in the winter areas of the North, Siberia, Kazakhstan and Far East.
To race around on skates at a speed of about hundreds of kilometers per hour, it is not necessary to have some special sports data or gigantic physical strength. “Tailor” yourself “wind coat”, and you will achieve this without the use of any significant physical effort.
This mixer is mainly intended for making babies infant formula, whipping small batches of dessert cocktail or puree fruits and vegetables with the pulp.
Every year increases the number of syt and Palaces of pioneers, where the pipeline automodelismo. During the construction of trails is often necessary to perform smooth transitions from concentric circles to parallel straight, which causes some difficulties. At the station of young technicians of the Leningrad district of the city of Yerevan was built trendoriginal track. Today we decided to share our experience of graphical representation of the curves of the track.
Induction coil, in the last century invented Rumkorem, and is now used in experiments in physics. But now it is not fully satisfy the requirements of physical experiment creates interference, does not regulate the high voltage. consumes battery power, and feed the coil directly from the mains AC is impossible. We offer you to equip physical classrooms modernized version of the instrument developed on the basis of electronics.
I want to share with readers the experience of recovery separator sealed bearings in the field of wire inserts for the distribution of balls in the clip with the desired step. This will help prolong the lifespan of many machines and mechanisms without removing and replacing the bearings. I ran into this when, after several years of operation of the drill in it was destroyed separators sealed bearings of the rotor of the motor.
