    Extension = (Final length - Initial length) / initial length = -1.86/47.42 = -0.039 Stretch= 1+extension = 1-0.039= 0.961 Refer to the attached figure for the formula.

  • Sajan sarthak sahoo thankyou
    Extension is the( final - initial) so 45.56-47.42= -1.86 so here negative extension means compression Stretch is final /initial 45.56/47.42=0.960

    but I think formula of stretch is final-initial/initial
