Question $9$

UPLOAD is NOT expected

Given reaction components of $Cx$ and $Cy$ at $C$ and that the pin at $C$ has cross$-$sectional area :

What in the aumma chesr etrece in the nin C$?$

$({}_C{)}_{\text{a}\text{v}\text{g}}=\frac{\sqrt[\phantom{2}]{C_x^2+C_v^3}}{4A}$

$({}_C{)}_{\text{a}\text{v}\text{g}}=\frac{\sqrt[\phantom{2}]{C_x^3+C_p^3}}{A}$

$({}_C{)}_{\text{a}\text{v}\text{g}}=\frac{\sqrt[\phantom{2}]{C_x^2+C_v^2}}{3A}$

$({}_C{)}_{\text{a}\text{v}\text{g}}=\frac{C_x+C_y}{2A}$

$({}_C{)}_{\text{a}\text{v}\text{g}}=\frac{C_x+C_v}{A}$
