Question

Decide whether the statements about thin-walled pressure vessels are true or false. Write the relevant equations to support your decision. If the statement is false, correct it. a. Circumferential, Hoop, and Second Principle stress are all equivalent names for the same term. b. Longitudinal stress is twice the value of circumferential stress. c. The ratio between external radius and wall thickness >10 d. Shear stress is always twice the value of its corresponding normal stress. e. Maximum longitudinal normal stress is four times greater than maximum spherical shear stress.
