Muu nimi/muut nimet:Testing the Aeroplanes A 12 through Loading the Load-Bearing System up to Breaking
Kuvaus:The film begins with shots of aeroplanes A 12 prepared in a hangar for the strength tests. With bags of sand the workers step by step weight up the wings of the aeroplane. With more layers of weights, sagging of the girders increases. With the seventh layer of bags weighing 8080 kg, the wing of the plane breaks. The course of the preparations for the strength tests of the fuselage of the aeroplane lies in its weighting with iron loads. With the fourth layer, the fuselage of the aeroplane gets deformed under the strain of the load. The camera also shoots a military commission watching the test from benches placed outside the hangar and generals Čeček and Kolařík in a lively discussion. Finally, the landing gear is tested for strength while its axis bears down with the weight increased, however, it does withstand the load.
