5 Consider The Tensile Stress Strain Diagrams In Figure Shown Labeled 1 And 2 These 2894868

5- Consider the tensile stress–strain diagrams in Figure shown labeled 1 and 2. These diagrams are typical of metals. Answer the following questions, and consider each part as a separate question that has no relationship to previous parts of the question. (a) Samples 1 and 2 are identical except for the grain size. Which sample has the smaller grains? How do you know? (b) Samples 1 and 2 are identical except that they were tested at different temperatures. Which was tested at the lower temperature? How do you know?
