Problem $10$:

The spring mechanism is used as a shock absorber for a load applied to the drawbar $AB.$ Determine the force in each spring when the $50-kN$ force is applied. Each spring is originally unstretched and the drawbar slides along the smooth guideposts $CG$ and $EF.$ The ends of all the springs are attached to their respective members. Also, what is the require diameter of the shank of bolts $CG$ and $EF$ if the allowable stress for the is ${}_{\text{a}\text{l}\text{l}\text{o}\text{w}}=150$MPa

Ans:

$F_H=20kN$

$F_{BF}=F_{AG}=15\mathrm{.}0kN$

$d_{EF}=d_{CG}=11\mathrm{.}3mm$
