The two I-beams are welded together and are initially supported by the three cables of equal length hanging vertically from supports directly above \( A, B \), and \( C \). When applied with the appropriate offset \( d \), the 255 - N force causes the system to assume the new equilibrium configuration shown. All three cables are inclined at the same angle \( \theta \) from the vertical, in planes parallel to the \( y-z \) plane. Determine this deflection \( \theta \) and the proper offset \( d \). Beams \( A B \) and \( O C \) have masses of 68 kg and 55 kg , respectively. The mass center of beam OC has a y-coordinate of 755 mm . Answers: \( \theta= \) \( d= \) mm
