One of the smooth vertical walls supporting end B of the 205-kg uniform shaft is turned through a \( 26^{\circ} \) angle as shown here. End \( A \) is supported by the ball-and-socket connection in the horizontal \( x \) - y plane. Calculate the magnitudes of the forces \( P \) and \( R \) exerted on the ball end \( B \) of the shaft by the vertical walls \( C \) and \( D \), respectively. Assume \( a=5.4 \mathrm{~m}, b=1.6 \mathrm{~m}, \mathrm{~L}=6.1 \mathrm{~m} \), and \( \theta=26^{\circ} \). Answers:
