A flat 1018 steel sample was tested in a tensile machine. Sample dimensions are width = 0.425 inch, thickness = 0.175 inch, original gauge length = 3.45 inch. The sample shows yielding when 3300 lb force is applied with a corresponding change in length of 0.06 inch. From the data, the greatest force applied during testing was 4500 lbs and the sample had elongated by total of 0.5 inch. At fracture, the force applied to the sample decreased to 3000...

Problem 1: A round bar with a diameter of 29 mm, and 4880 mm in length was under tensile test to determine the mechanical properties of the material. The following table shows the load versus strain data collected from the testing machine and a strain gauge applied on the bar in the loading direction. The measured percentage elongations were 19.4 % and 14.2 % on gauge lengths of 100 mm and 200 mm respectively. Assume: the elongations include the necking:...

2) Construct 95% Confidence Intervals for the PERCENTAGE of
Aluminum ductility and Steel ductility. TREAT THE PERCENTAGE DATA
AS REGULAR DATA VALUES, AND NOT AS PROPORTIONS AS I SUGGESTED
EARLIER. What can you say about the typical proportion ductility
for Aluminum with respect to Steel? From a statistically
significant perspective, can you conclude the Aluminum ductility is
greater than Steel ductility based upon these CIs?

Due to the operational conditions and temperature gradient, a 95 mm diameter, 1.75 m long steel rod within a machine assembly is subjected to a combination of tensile loading of 190 N and thermal loading which imposes a longitudinal force of 244 N. The total loading results in an even distribution of forces on the body of the rod causing it to change its dimensions by increasing 0.45 mm in length at both ends and decreasing by 0.0135 mm at...

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.
Thanks
