Unless otherwise noted in the following problem, assume that the beam cross section is oriented so the strong axis is the bending axis.
A timber power-line pole is 10 in. in diameter at its base where it is solidly embedded in concrete. The pole extends 20 ft vertically upward from its base and is subjected to a horizontal pull of 300 lb at its top. Calculate the maximum bending stress and the maximum shear stress produced in the pole.
