Dayanara Alicia Castillo$-$

HW$4\mathrm{.}6.$ Shear Stress in a Pin $-$ Bar and Bracket $($revised$)$

The rigid, horizontal bar ABC is supported by a rigid, weightless link $EB$ and pinned to a wall at $A.$ Link $EB$ is pinned at both ends $E$ and $B.$ Bar ABC is subjected to a triangular distributed load with $w=5\frac{N}{m}m.$

Consider the following dimensions:

$a=721mm,c=641mm,$ and $L=1602mm$

Determine the magnitude of the average shear stress at pin $E_{,}|{}_E|.$ The pin at $E$ is in double shear and has cross$-$sectional area $A_E=57m{m}^2.$

$|{}_E|=$

MPa
