A strut CB is guyed back to a wall support through cable BA. Two forces are applied to the concurrent joint at B. Determine the tension in cable BA and the force in member CB for a condition of equilibrium to occur.

First step: construct a FBD of the concurrent joint B.

Intuitively, guess at the direction for each of the two unknown forces.

Incorrect assumptions about the force directions will be revealed at the end of the process with a negative answer.

A negative sign simply mean that the direction of the force was incorrectly assumed in the initial FBD, however, the magnitude remains unaffected.
