Writing as an Engineer Homework 2, Spring 2011
This homework assignment is providing you with an opportunity to demonstrate your ability to make plots with computer software. It is at your will to choose any graphing software as long as you make sure that the plot you generated meets the following requirements: 1. The plot should be no smaller than a half-page size. 2. There should be no filled-color inside the frame of the plot. 3. There should be no horizontal and vertical grids inside the frame of the plot. 4. A figure caption should be included. 5. All texts and labels associated with the plot should not have a font-size smaller than 14. 6. It is desirable that all texts and labels use Times New Roman font style. 7. Equation should be shown in case curve fitting, such as linear regression, is used, and the fonts size for the equation should be bigger than 14 also. 8. The frame and ticks for the plot should be thick enough for reproduction in publication. The thickness should match the font size in the plot. 9. If color is used, the color of the curve should be dark enough for printing in black and white. 10. Symbols should have a compatible size and color with each set of data. 11. A legend with correct font size and color and frame requirement is desirable. In this homework, you are required to make a plot base on the following experimental data. (1) A specimen of magnesium having a rectangular cross section of dimensions 3.2mm×19.1mm (1/8 in. × 3/4 in.) is deformed in tension. The load-elongation data are tabulated as follows. Load lbf 0 310 625 1265 1670 1830 2220 2890 3170 3225 3110 2810 N 0 1380 2780 5630 7430 8140 9870 12850 14100 14340 13830 12500 Fracture in. 2.500 2.501 2.502 2.505 2.508 2.510 2.525 2.575 2.625 2.675 2.725 2.775 Length mm 63.50 63.53 63.56 63.62 63.70 63.75 64.14 65.41 66.68 67.95 69.22 70.49

(2) A cylindrical specimen of aluminum having a diameter of 0.505 in (12.8 mm) and a gauge length of 2.000 in. (50.800mm) is pulled in tension. The load-elongation data are tabulated as follows. Load lbf 0 1650 3400 5200 6850 7750 8650 9300 10100 10400 10650 10700 10400 10100 9600 8200 N 0 7330 15100 23100 30400 34400 38400 41300 44800 46200 47300 47500 46100 44800 42600 36400 Fracture Please complete: (a) Plot the data as engineering stress versus engineering strain for both specimens on the same plot with different symbols and color. (b) Compute the modulus of elasticity of each specimen using linear regression provide by your software. Make sure you comply with the requirement when linear regression is used. (c) Determine the yield strength at a strain offset of 0.002 for each specimen and label the σ0.2 values, respectively, on your plot for each specimen. Note: I only need one plot for this homework. Therefore, everything should appear on one plot only. Please make proper arrangement and generate a nice-looking and professional plot that can be used for publication. in. 2.000 2.002 2.004 2.006 2.008 2.010 2.020 2.040 2.080 2.120 2.160 2.200 2.240 2.270 2.300 2.330 Length mm 50.800 50.851 50.902 50.952 51.003 51.054 51.308 51.816 53.832 53.848 54.864 55.880 56.896 57.658 58.420 59.182
