The bent rod is supported at A$,$ B$,$ and C

by journal bearings, as shown in $($Figure $1).$ The rod is subjected to the vertical force P$=260$ lb and the couple moment M

$=20$ lb$$ft$.$ The bearings are in proper alignment and exert only force reactions on the rod.

$1)$Determine the components of reaction at the bearing A

$2)$Determine the components of reaction at the bearing B

$3)$Determine the components of reaction at the bearing C
