The strain-stress plot for materials A, B, C and D is shown in the figure. Which material has the largest Young's modulus ?

Options

  1. AD
  2. BB
  3. CC
  4. DA

Correct answer

C. C

Step-by-step solution

Young's modulus ( Y ) is defined as the ratio of stress to strain: Y = stress strain . In the given graph, the y-axis represents strain and the x-axis represents stress. The slope of the line in a strain-stress graph is given by m = strain stress . Therefore, Y = 1 slope . To have the largest Young's modulus, the material must have the smallest slope in the strain-stress plot. From the figure, line C has the smallest angle with the stress axis (x-axis), meaning it has the minimum slope. Since Y 1 slope , material C
