Apprentices were asked to carry out tests on the shelter frame angle iron material - it was suspected to be carbon steel, AISI 1006 grade. Test pieces were taken to a local workshop equipped with Hounsfield Tensometer and Vickers Hardness testing capability. The test piece dimensions were: 100 mm long by 5 mm thick by 20 mm wide. The test results were: Tensometer Test Yield Force/kN 21.0 20.5 20.4 21.6 21.5 1 35.0 2 33.0 3 32.5 4 30.0 5 34.5 In addition, during the test, it was noted that an applied load of 10.3 kN produced an extension of 0.05 mm. Vickers hardness - Test Load/kg 1 2 3 4 5 Max Force/kN 50 50 50 50 50 Diagona 1 ave/mm 1.00 0.99 0.97 0.96 0.93 Using the test data, determine average values for the yield stress and ultimate tensile stress. Calculate values of Young's Modulus and Vickers hardness for the metal.
