1-74. The spring mechanism is used as a shock absorber for a load applied to the drawbar \( A B \). Determine the force in each spring when the \( 50-\mathrm{kN} \) force is applied. Each spring is originally unstretched and the drawbar slides along the smooth guide posts \( C G \) and \( E F \). The ends of all springs are attached to their respective members. Also, what is the required diameter of the shank of boits \( C G \) and \( E F \) if the allowable stress for the bolts is \( \sigma_{\text {allos }}=150 \mathrm{MPa} \) ?
