In the world of modern industrial production on a prosaic bearings start to forget. However, for rotating parts of virtually any desired mechanism ball bearings. They are in household appliances, factory machines and even car engines.
On the video you can see deep groove ball bearing with deep groove. It steel balls move along the slotted rings of solid steel. The balls are made of the same steel.
TANK SU-122. Scale model 1:25.
Self-propelled gun SU-122 was developed in November 1942, the design Bureau of UZTM under supervision of L. I. Gorlitskiy. Leading engineer of the car was N. In. Kurin. A sample of the plant (factory designation I-35) was made on November 30, 1942 After the factory test, in the first half of December of the same year self-propelled unit has passed the state tests Gorokhovetsky Anope. On the arms were adopted on 5 December 1942 the Serial production started in December 1942 and lasted until August 1943 and All were released 638 self-propelled guns.

Three-dimensional, or 3D printer is the output device a three-dimensional data (typically, three-dimensional geometry). The result is some physical object, the prototype.
There are several 3D printing technologies, but the basis of any one of them is the principle of creating a layered solid geometry.
The principle of operation of 3D-printers Z Corporation more similar to a conventional inkjet printer. The main difference is that instead of applying ink from the printhead to the next sheet of paper into a 3D printer binder through the printhead is applied to another thin (about 0.1 mm) layer of powder, creating a single cross section of the object.
Van (eng. minivan – “small van”) – passenger car with one-volume body hoodless (less – car) or polutorapolnoy (polkapete) layout, usually with three rows of seats.

Well, in our country roads has always been a problem. Consequently, problems arose and the designers who had to think about what road they should design new cars.
Simple home technology allows to obtain a universal adhesive, which is applicable for the connection details from a variety of materials.
For its production is taken linoleum old varieties, crushed and filled with acetone for 10-12 hours. After dissolving, the glue is ready to use, and the density of it is adjustable by adding one of the components or by mixing powdered fillers (chalk, talc, sand).
