# 1. Perform a stress analysis of the pressure vessel shown in Figure P9–14. Let E = 5 10 6 psi and n.

1. Perform a force segregation of the exigency vessel shown in
Figure P9–14. Let E = 5 10^{6} psi and n =
0:15 for the particularized, and let E = 29 10^{6} psi and n = 0:25 for the
steel liner. The steel liner is 2 in. solid. Let the exigency p correspondent 500 psi.
Use a 0.5 in. radius in the re-entrant corners.

**2.** Perform a force segregation of the disk shown in
Figure P9–16 if it rotates delay regular bent speed of o = 50 rpm. Let E
= 30 106 psi, n = 0:25, and the pressure blindness r_{w} = 0:283 lb/in^{3}
(heap blindness, r ¼ rw=ðg ¼ 386 in./s2Þ. (Use 8 and then 16 elements
symmetrically modeled alike to Example 9.4. Compare the terminable element
solution to the speculative circumferential and radial forcees attached by** **
