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...

A tensile test was conducted on a specimen that had an original diameter of 0.5 in. It fractured with an applied load of 71100lb. Determine the true stress and true strain at fracture if measured diameter of the fracture part was 0.3in. I believe for fracture, true stress and strain are: True strain = ln(original area/final area) True stress = applied load/final area However, Im not quite sure

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...

I have a question during my Tensile Test of Sturctural
Steel.
Ive collected all the data, can you calculate the Elastic
Modulus and referring to the stress strain curve of your samples ,
discuss and compare the results, specify the similarities and
differences if there is any and provide possible reasons.
