Dimensions of stress are :
  1. A
    [ML2T−2]\left[ {M{L^{ 2}}{T^{ - 2}}} \right][ML2T−2]
  2. B
    [ML0T−2]\left[ {M{L^{ 0}}{T^{ - 2}}} \right][ML0T−2]
  3. C
    [ML−1T−2]\left[ {M{L^{ - 1}}{T^{ - 2}}} \right][ML−1T−2]
  4. D
    [MLT−2]\left[ {M{L^{}}{T^{ - 2}}} \right][MLT−2]

Correct answer: C

Stress=ForceAreaStress = {{Force} \over {Area}}Stress=AreaForce​

=[MLT−2L2]=[ML−1T−2] = \left[ {{{ML{T^{ - 2}}} \over {{L^2}}}} \right] = \left[ {M{L^{ - 1}}{T^{ - 2}}} \right]=[L2MLT−2​]=[ML−1T−2]
