Group$-$riveted and Multi$-$row Joints Flabel: Example $3-2$

A pulley bracket is fastened to an auxiliary beam structure of the same material by means of four solid, protruding$-$head rivets, as shown in Fig. $330.$ During installation of this bracket, rivets $\backslash (\backslash$# $1\backslash )$ and $\backslash (\backslash$# $3\backslash )$ were drilled out to the next larger size. Find the shearing force reacted by each rivet for a maximum cable tension load of $400$ lb $.$ Also discuss the different possible modes of failure that may occur for this installation.
