Poisson's ratio of concrete μ can be determined using the formula:Whereas V is pulse velocity (mm/s), n is the resonant frequency of longitudinal vibration (Hz) & L is the distance between transducers (mm)

• A. \(\left( {\frac{V}{{2nL}}} \right) = \frac{{\left( {1 - \mu } \right)}}{{\left( {1 - 2\mu } \right)\left( {1 + \mu } \right)}}\)
• B. \(\left( {\frac{V}{{2\;nL}}} \right) = \frac{{\left( {1 + \mu } \right)}}{{\left( {1 - 2\mu } \right)\left( {1 + \mu } \right)}}\)
• C. \(\left( {\frac{{{V^2}}}{{2\;nL}}} \right) = \frac{{\left( {1 - \mu } \right)}}{{\left( {1 - 2\mu } \right)\left( {1 + \mu } \right)}}\)
• D. \(\left( {\frac{{{V^2}}}{{2\;nL}}} \right) = \frac{{\left( {1 - {\mu ^2}} \right)}}{{\left( {1 - 2\mu } \right)\left( {1 + \mu } \right)}}\)
