inner tubes, thus bringing acompressive stress on the latter which assists in resisting the tension dueto the internal pressure. For discussion of Lames, and other formulaefor built-up guns, see Merrimans Mechanics of Materials. THIN CYLINDERS UNDER TENSION. Let p = safe working pressure in lbs.… … 14,000 The above represents the strength resisting rupture along a longitudinalseam. For resistance to rupture in a circumferential seam, due to pressure on the ends of the cylinder, we have ^-r— = —^—; 4Ttc whence p = —rz—• Or the strength to resist rupture around a circumference is twice as…
