Which one of the following is not a unit of Young's modulus ?

Question

Which one of the following is not a unit of Young's modulus ? (A) Nm-1 (B) Nm-2 (C) dyne cm-2 (D) Mega Pascal

Tardigrade Admin · Accepted Answer

y=( text stress / text strain )= N / m 2 or pascal (in SI system) and y=( text dyne / cm 2) (in CGS. system) Thus, Nm -1 is not the unit of Young's modulus

Q. Which one of the following is not a unit of Young's modulus ?

$N m^{- 1}$

$N m^{- 2}$

dyne $c m^{- 2}$

Mega Pascal

$y = \frac{stress}{strain} = N / m^{2}$ or pascal (in SI system)
and $y = \frac{dyne}{c m ^{2}}$ (in CGS. system)
Thus, $N m^{- 1}$ is not the unit of Young's modulus

Q. Which one of the following is not a unit of Young's modulus ?

Nm−1

Nm−2

dyne cm−2

Mega Pascal

y= strain stress ​=N/m2 or pascal (in SI system) and y=cm2 dyne ​ (in CGS. system) Thus, Nm−1 is not the unit of Young's modulus

$N m^{- 1}$

$N m^{- 2}$

dyne $c m^{- 2}$

$y = \frac{stress}{strain} = N / m^{2}$ or pascal (in SI system)
and $y = \frac{dyne}{c m ^{2}}$ (in CGS. system)
Thus, $N m^{- 1}$ is not the unit of Young's modulus
