9. Τhe figure shows a vertically loaded support which is connected to a hinged member with three identical bolts. Although normally the load of 24 kN is applied at the center, the selection of bolts should be made assuming the load eccentricity indicated in the figure. Due to safety concerns, the specification calls for SAE grade 9.8 steel bolts and a minimum safety factor of 6. Find the right size bolt for this application (Give answer in the following form: Mx x y)
