It is desired to evaluate the tensile properties of an aluminum alloy. A tensile test is performed using a standard cylindrical tensile specimen with a diameter of 12.8 mm and a gauge length of 50.800 mm. The gage length and final diameter of the sample are measured after the sample is removed from the testing machine. The gage length and the diameter of the necked region after the specimen was removed from the testing machine are 60 mm and 9...

A tensile test of a metal was run in the laboratory, but only the maximum load was measured during the test (max load = 59 kN). All other data were taken before and after the test as follows: 2. 13.0mm 10.0mm Initial diameter: Minimum diameter after test (at point of fracture) Maximum diameter after test (away from fractur): 116mm Calculate: a. The strain hardening exponent, n, in the power relation j = HE". b. The load on the specimen at...

Assignment 01 TOT Mechanical Properties of Materials 1. A tensile test specimen has a gage length = 50 mm and its cross-sectional area = 100 mm. The specimen yields at 48,000 N, and the corresponding gage length - 50.23 mm. This is the 0.2 ent yield point. The maximum load of 87,000 N is reached at a gage length 64.2 mm. Determine (a) yield strength, (b) modulus of elasticity, and (c) tensile strength. (d) If fracture occurs at a gage...
