A tensile test is performed on an aluminum specimen 10 mm in diameter using a gauge length of 50 mm. When the tensile force, F, reaches a value of 20 kN, the distance between the gage marks increases by 0.122 mm. Point out whether the specimen diameter decreases or increases if the Poisson's ratio is 0.34.

His can you find answers for these please and explain how ? Thank you

Hello, the stress and cycles required for this question is Stress 1 = 420MPa at 7 cycles, Stress 2 = 360MPa at 65 cycles and Stress 3 = 130MPa at 325 cycles. Use the first three cycles (which shows how many cycles at that stress level to failure) to calculate when the specimen will fail if it underwent test of 7 cycles at 420MPa, then undergoes 360MPa for 65 cycles and finally 130MPa at 325 cycles. Will the specimen fail? Please show calculations of failure

A tension test was performed on a specimen having an original diameter of 13.7 mm and a gauge length of 50 mm. The data are listed in the table.
