Multiple Choice

Answer 1

Cylindrical Pressure Vessel Let t = radius of pressure vessel Wall thickness + P = internal pressure The principal stresses developed inside pressure vessel are hoop stress [circumferential] longitudinal stress stress (on) stress acts of cylinder 1) Hoop The hoop along the circumference a 6h or ob Pet t 6h ón 2) Longitudinal stress (O) The longitudinal stress acts along the of a cylinder axis Pr oi at
