Solution to Problem 141 Pressure Vessel

$F = 85\,808.62 \, \text{lbs}$
 

$P = F$

$\sigma_l [ \, 2(2 \times 12) ( \frac{1}{8} ) + \pi (1.5 \times 12) ( \frac{1}{8} ) \, ] = 85\,808.62$

$\sigma_l = 6\,566.02 \, \text{psi}$

$\sigma_l = 6.57 \, \text{ksi}$           answer

$F = 5250L \, \text{ lbs}$
 

$2T = F$

$2[ \, \sigma_t ( \frac{1}{8} )L \, ] = 5250L$

$\sigma_t = 21\,000 \, \text{psi}$

$\sigma_t = 21 \, \text{ksi}$           answer
