There are $3$ forces acting on a ring. Determine the magnitude of

$$ and $$ that will result in the ring being in equilibrium. The

angle for $$ is provided. The horizontal and vertical components

of $$ create a similar triangle to a $3-4-5$ triangle.

Problem $2$:

Determine the moment that the $5$ kN force F on the end

of the rod causes about point O$.$
