Which of the following quantities has the same dimensional formula as that of modulus of rigidity?
- A.StressCorrect answer
- B.Strain
- C.Surface Tension
- D.Force
Solution
Modulus of rigidity is defined as the ratio of shearing stress to shearing strain. Since strain is a dimensionless quantity, the dimensions of modulus of rigidity are the same as that of stress and pressure ().
