Question
A rigid bar is supported by three non-rigid rods, as shown. There is no initial strain and the length of Rods A and C is
0.7 m, while Rod B is 0.9 m. A 45 kN downward load is applied to the rigid bar, equally resisted by Rod A, B, and C.
Clearly show ALL FBDS used.

1. Determine the average shear stress in the \(10\;mm\)-diameter pin segment at P. Given is a side view, viewed from
plane S. An incomplete FBD of the pin segment is also shown.
