A 12.5-mm round structural steel rod is loaded in tension to fracture. The 200-mm gage length of the rod was marked off in 25-mm lengths before loading. After the rod broke, the strain in the 50-mm containing the fracture was found to be 0.45 mm/mm, and the total elongation of the other 150 mm was found to be 37.5 mm. Determine the average strain for the 200-mm gage length.

A tensile test was performed on a metal specimen with a diameter of 1 2 inch and a gage length (the length over which the elongation is measured) of 4 inches. The dam were plotted on a load-displacement graph. P vs. L. A best-fit line was drawn through the points, and the slope of the straight-line portion was calculated to be P/L =1392 kips/in. What is the modulus of elasticity?
The data in Table 1.5.3 were obtained from a tensile test of a metal specimen with a rectangular cross section of 0.2011in.2 in area and a gage length (the length over which the elongation is measured) of 2.000 inches. The specimen was not loaded to failure. a. Generate a table of stress and strain values. b. Plot these values and draw a best-fit line to obtain a stress-strain curve. c. Determine the modulus of elasticity from the slope of the linear portion of the curve. d. Estimate the value of the proportional limit. e. Use the 0.2 offset method to determine the yield stress.

dont round off. there should be three answers and the maximum thickness
Thanks sir
