Problem 2.23 - Average Shear Stress

Problem Statement

A square bar of length L₁ = 10 in. and L₂ = 14 in. is pinned at one end and rests on a circular rod of diameter d = 5/8 in. A force F = 60 lb is applied at the free end. What is the average shear stress in the circular rod?

Picture with a circular rod pinned at one end and resting on a circular rod at a distance L1 from the wall. The other end of the rod has a force applied downward. [Problem adapted from © Kurt Gramoll CC BY NC-SA 4.0]
