Question $4$

The space $($noncoplanar$)$ structure presented is supported by ball$-$and$-$socket joints at $O$ and $D,$ and by a slider bearing at $C.$ The two rigid members, OABC and $AD,$ connected by a ball$-$and$-$socket joint at $A,$ each have a mass of $75k\frac{g}{m}.$ Determine the magnitude of the reaction force components at $O$ and $C.$

Answers:

$O_x=1\mathrm{.}820kN$

$O_y=2\mathrm{.}72kN$

$O_z=-0\mathrm{.}77kN$

$C_x=-1\mathrm{.}820kN$

$C_z=0\mathrm{.}33kN$
