Chapter 8, Problem 8.5.14P
A post having a hollow, circular cross section supports a P = 3.2 kN load acting at the end of an arm that is h = 1.5 m long (see figure). The height of the post is L = 9 m, and its section modulus isS = 2.65 x 10 mmJ. Assume that the outer radius of the post is r2= 123 mm, and the inner radius is r}=117 mm.

maximum in-plane shear stress Tm:ls at point A on the outer surface of the post along the x axis due to the load P. Load P acts at B along line BC.

The elastic bar from Problem 1 spins with angular velocity ω about an axis, as shown in the figure below. The radial acceleration at a generic point x along the bar is a(x) = ω 2 x. Under this radial acceleration, the bar stretches along x with displacement function u(x). The displacement u(x) is governed by the following equations: ( d dx (σ(x)) + ρa(x) = 0 PDE σ(x) = E du dx Hooke’s law (2) where σ(x) is the axial stress in the rod, ρ is the mass density, and E is the (constant) Young’s modulus. The bar is pinned on the rotation axis at x = 0 and it is also pinned at x = L.
