Collars A and B are connected by $25$ in long wire and can slide freely on frictionless rods. If

a $60$ lb force $Q$ is applied to collar $B$ as shown, determine $($a$)$ the tension in the wire when

$x=9$ in and $z=12in,($b$)$ the corresponding magnitude of the force $P$ required to maintain

equilibrium of the system.
