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...

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...
