For the axisymmetric connecting rod shown in Figure P9-18, determine the stresses z , r

For the axisymmetric connecting rod shown in Figure P9-18, determine the stresses σ_z, σ_r, σ_θ, and τ_rz. Plot stress contours (lines of constant stress) for each of the normal stresses. Let E = 30 × 10⁶ psi and v = 0.25. The applied loading and boundary conditions are shown in the figure. A typical discretized rod is shown in the figure for illustrative purposes only.
