The load versus elongation graph for four wires of the same materials shown in the figure. The thinnest wire is represented by the line

Options

  1. AO C
  2. BO D
  3. COA
  4. DO B

Correct answer

C. OA

Step-by-step solution

It is clear from the graph that, for same value of load (F) , elongations q , l₂, l₃, l₄ are such that l₄>l₃>l₂>l₁ So, OA represents the thinnest wire.
