The horizontal boom is supported by the cables \( A B \) and \( C D \) and by a ball-and-socket joint at \( O \). Neglect the weight of the boom. A vertical force \( L=10 \mathrm{kN} \) is applied as shown. Determine the tension in each cable (magnitudes) and the magnitude of the reaction at \( O \). \[ F_{A B}= \] \[ F_{C D}= \] Magnitude of reaction at \( O= \)
