Question

The dimensional formula for stress is –

• A. $\lbrack M^{0}L^{1}\text{T}\text{ }^{\text{-2}}\rbrack$
• B. $\lbrack M^{0}L^{\text{-1}}\text{T}\text{ }^{\text{-2}}\rbrack$
• C. $\lbrack M^{0}L^{2}T^{1}\rbrack$
• D. $\lbrack\text{M}\text{L}^{\text{-2}}\text{T}\text{ }^{\text{-1}}\rbrack$

Answer 1

Answer: (B)

$\lbrack M^{0}L^{\text{-1}}\text{T}\text{ }^{\text{-2}}\rbrack$

Answer 2

$\mathbf{\lbrack}\mathbf{M}^{\mathbf{1}}\mathbf{L}^{\text{-1}}\text{T}\text{ }^{\text{-2}}\mathbf{\rbrack}$
