Example:

$-$ The rigid frame ADB is supported by a bearing$-$like bracket at point $\backslash ($ A $\backslash )$ and $\backslash ($ a $\backslash )$ vertical cable at point $\backslash ($ B $\backslash ).$ The bracket at point A allows the frame to freely rotate about the x$-$axis but restricts all other translation and rotation of the frame. Determine the reactions at point $\backslash ($ A $\backslash )$ and the tension in cable $\backslash ($ B C $\backslash )$ needed to support the applied vertical force $\backslash ($ F $\backslash ).$
