It is assumed that bolt B is $\frac{3}{4}-123$ and bolt A is $\frac{3}{8}-123,$ ASTM A$325.($a$)$ Determine the stress developed in the bolts based on the following figure and check if the bolts can handle the load. $($b$)$ Redesign the bolts based on available sizes $($just by increasing the area$)$ so that the bolts can handle the load. You need to show new design is safe for all bolts. $($Allowable shear stress for ASTM A$325$ is $30$ksi $).$
