General Studies · Thin Cylinders
What is the correct formula for hoop strain (εH) in thin-walled cylindrical pressure vessels, where σh is the hoop stress, σL is the longitudinal stress, μ is Poisson's ratio, and E is the elastic modulus of the material?
- 1εH = 12E [σh - μσL]
- 2εH = 1E [σh - μσL]✓
- 3εH = 15E [σh - μσL]
- 4εH = 13E [σh - μσL]
Correct answer
εH = 1E [σh - μσL]
