Solve the following axisymmetric problems using a computer program.

Perform a stress analysis of the disk shown in Figure P9–16 if it rotates with constant angular velocity of ω = 50 rpm. Let E = 30 × 10⁶ psi, n = 0.25, and the weight density ρw = 0.283 lb/in³ (mass density, ρ = ρ_w/(g = 386 in./s2). (Use 8 and then 16 elements symmetrically modeled similar to Example 9.4. Compare the finite element solution to the theoretical circumferential and radial stresses given by
