Bending and circumferential stress-Cylinder

[har_rai]

Homework Statement

How do we combine bending stress on thick walled cylinder from external point load or moment to other longitudinal, radial and hop stresses which are from pressurized thick walled cylinder. Since bending stress and longitudinal stresses are in the same direction, do we just add hose. or if hoop stresses significantly higher than bending stress, we just say cylinder is critical for hoop stress.

Stresses that act in the same direction can be added algebraically. Do bending stresses act in the same direction as hoop stresses?
