MCQ
The dimensional formula for the modulus of rigidity is
  • A
    $M{L^2}{T^{ - 2}}$
  • B
    $M{L^{ - 1}}{T^{ - 3}}$
  • C
    $M{L^{ - 2}}{T^{ - 2}}$
  • $M{L^{ - 1}}{T^{ - 2}}$

Answer

Correct option: D.
$M{L^{ - 1}}{T^{ - 2}}$
d
(d) Modulus of rigidity = $\frac{{{\rm{Shear}}\;{\rm{stress}}}}{{{\rm{Shear}}\;{\rm{strain}}}} = $ $[M{L^{ - 1}}{T^{ - 2}}]$
