MCQ
The dimensions of shear modulus are
- A$ML{T^{ - 1}}$
- B$M{L^2}{T^{ - 2}}$
- ✓$M{L^{ - 1}}{T^{ - 2}}$
- D$ML{T^{ - 2}}$
✓
Answer
Correct option: C.
$M{L^{ - 1}}{T^{ - 2}}$
c
(c) Shear modulus = $\frac{{{\rm{Shearing\, stress}}}}{{{\rm{Shearing\, strain }}}}$ $ = \frac{F}{{A\theta }} $ $= [M{L^{ - 1}}{T^{ - 2}}]$
(c) Shear modulus = $\frac{{{\rm{Shearing\, stress}}}}{{{\rm{Shearing\, strain }}}}$ $ = \frac{F}{{A\theta }} $ $= [M{L^{ - 1}}{T^{ - 2}}]$
