Problem $2$:

The space truss shown models an airplane's landing gear. It has ball$-$and$-$socket support at C$,$ D$,$ and E$.$ If the force exerted at A by the wheel is $F=40kN$ in y $-$direction. Determine:

a$.$ The axial forces in member $AB$ and $AD$

b$.$ The support reactions at $C$

Answer:

$a.T_{AB}(kN)=$

$-45\mathrm{.}37$

$T_{AD}(kN)=$

$7\mathrm{.}44$

$b.C_x(kN)=$

$C_Y(kN)=$

$C_Z(kN)=$
