Unformatted text preview: * 7. (a) The plot of impact energy versus temperature is shown below. * 8. =i'->-es II c: ~-U ! E (b) The average of the maximum and minimum impact energies from the data is 76 J + 2 J 2 = 39 J Average = n"-As indicated on the plot by the one set of dashed lines, the ductile-to-brittle transition temperature according to this criterion is about 10C. (c) Also, as noted on the plot by the other set of dashed lines, the ductile-to-brittle transition temperature for an impact energy of 20 J is about -2C....
