Assertion (A): For a thin cylinder under internal pressure, At least three strain gauges is needed to know the stress state completely at any point on the shell.
Reason (R): If the principal stresses directions are not know, the minimum number of strain gauges needed is three in a biaxial field. 
  • a)
    Both A and R are individually true and R is the correct explanation of A
  • b)
    Both A and R are individually true but R is NOT the correct explanation of A
  • c)
    A is true but R is false
  • d)
    A is false but R is true
Correct answer is option 'D'. Can you explain this answer?

For thin cylinder, variation of radial strain is zero. So only circumferential and longitudinal strain has to measurer so only two strain gauges are needed.
