Question

5-86 The sign has a mass of 100 kg with center of mass at \( G \). Determine the \( x, y \), and \( z \) components of reaction at the ball-and-socket joint \( A \) and the tension in wires \( B C \) and \( B D \). Answer: \( A_{x}=0, A_{y}=589 \mathrm{~N}, A_{z}=490 \mathrm{~N} \), \( F_{B D}=249 \mathrm{~N}, F_{B C}=589 \mathrm{~N} \)
