Draw FBD (required for each problem!) and use equations of equilibrium to determine the reaction forces and moments Problem 1.2-19 A \( 150-\mathrm{lb} \) rigid bar \( A B \), with frictionless rollers at each end, is held in the position shown in the figure by a continuous cable \( C A D \). The cable is pinned at \( C \) and \( D \) and runs over a pulley at \( A \). (a) Find reactions at supports \( A \) and \( B \). (b) Find the force in the cable.
