고체역학 (Gere) — Stresses in Beams (Basic Topics): Problem 5.9-3

5.9-3 A vertical pole consisting of a circular tube of outer diameter 127 mm and inner diameter 115 mm is loaded by a linearly varying distributed force with maximum intensity of \( q_0 \). Find the maximum shear stress in the pole. (From the accompanying figure, \( q_0 = 5.8 \text{ kN/m} \) and the length of the pole \( L = 3 \text{ m} \)).
