Figure for question 80, ISRO Mechanical & Aerospace 2017-2

  • A. A-L, B-N, C-M
  • B. A-N, B-L, C-M
  • C. A-M, B-N, C-L
  • D. A-N, B-M, C-L

Answer: B. A-N, B-L, C-M

Explanation: A. Maximum shear stress criterion corresponds to the Tresca hexagon (Representation N). B. Maximum distortion energy criterion (von Mises) corresponds to the ellipse (Representation L). C. Maximum normal stress criterion (Rankine) corresponds to the square (Representation M). Thus, the correct match is A-N, B-L, C-M.
