S kolikšno silo F smo obremenili vzorec, če upoštevamo, da smo ostali v elastičnem območju kjer velja Hookov zakon. Za modul elastičnosti (Youngov modul) vzamemo vrednost E= 72000MPa. Preizkušanec pa je imel pravokoten presek velikosti a=12mm in b=3mm ter začetno dolžino preizkušanca L=80mm, ta pa se je med obremenitvijo raztegnila za 0,1%. .
Končne koordinate izračunate po formuli:
N 46° 23,(F-A+B*6+13)
E 015° 33,(F/6-C*3-112)
Povečano število muglov med urami 5:30-7:30, 13:30-16, 21:30-22:30 !!

ENG:
The cache is located in the vicinity of company X, where for many years a variety of processed aluminium products and semi-finished products ( such as foil, profiles, bars, pipes, sheets, etc.) are produced.
Your task is to determine the name of the company and answer the following questions:
A = Which year was the company X founded. A =~~~~.
B = Change the 3. letter of the company name to a number (English alphabet)
C = Which material was processed when the company was first founded?
• steel = 4
• copper = 9
• aluminium = 15
• lead = 1
In company X they cast aluminium with different chemical compositions and different mechanical properties. Each alloy should be tested whether it actually complies with the required properties. One of these tests is the tensile test. This determines how much can the material be loaded without suffering permanent deformation and the load at which the test sample breaks. After the tensile test, we get a diagram (stress-strain curve) that you can see in the picture above (example is for aluminium).
What force F was exerted on the sample, considering that we stayed in the elastic range where Hooke's law holds. For the elastic modulus (Young’s modulus) take the value of E = 72000MPa. The specimen has had a rectangular cross-section of the size a = 12mm and b = 3 mm, and the initial specimen length was L = 80 mm. The length increased under load by 0.1%.
Calculate the final coordinates according to the equation:
N 46° 23,(F-A+B*6+13)
E 015° 33,(F/6-C*3-112)
There's an increased number of muggles in the area between the hours of 5:30-7:30, 13:30-16, 21:30-22:30!!
