The strain stress curves of three wires of different materials are shown in the figure. P , Q and R are the elastic limits of the wires. The figure shows that

Options

  1. Aelasticity of wire P is maximum
  2. Belasticity of wire Q is maximum
  3. Ctensile strength of R is maximum
  4. DNone of the above is true

Correct answer

C. tensile strength of R is maximum

Step-by-step solution

On the graph stress is represented on x -axis and strain y -axis So from the graph y= = 1 1 [where, is the angle from stress axis] Y_P Y_Q Y_R [ As _P _Q _R ] We can say that elasticity of wire P is minimum and R is maximum.
