Dimensions of stress are: (a) [ML²T⁻²] (b) [ML⁰T⁻²] (c) [ML⁻¹T⁻²] (d) [MLT⁻²]

Answer: (c). Stress = F/A [stress] = [MLT⁻²][L²] = [ML⁻¹T⁻²] So the answer is (c).

Dimensions of stress are:

Show answer and solution

Answer: (c)

Stress $= \frac{F}{A}$
$[\text{stress}] = \frac{[\mathrm{MLT^{-2}}]}{[\mathrm{L^2}]} = [\mathrm{ML^{-1}T^{-2}}]$
So the answer is (c).
