2.1 In a tensile test, the flow curve parameters for a metal alloy were determined as follows: strength coefficient =700MPa and strain-hardening exponent =0.25. The same metal is now put to the test in a compression test with starting specimen dimensions of 30mm in diameter and 70mm in height. Find the load needed to compress the specimen to a height of 60mm while if, the cross section increases equally. 2.2 True strain in a tensile test on a steel specimen is equal to 0.15 at 350MPa true stress and 0.20 at 420MPa true stress. In the flow curve equation, ascertain the strength coefficient and strain-hardening exponent
