 a). The circumferential stress on the outside layer
 b). The circumferential stress on the inside layer
 c). The longitudinal stress
 d). The circumferential strain in the outside layer
 e). The circumferential strain in the inside layer
 f). The change in the inner diameter
 g). The change in the outer diameter
