This concerns analysis of the shear stress at the outer most fasteners from the centroid of the fastener grouping. The analysis is an included attachment. Schaum's outline was helpful in resolving this problem.
The line of action for this configuration is eccentric to the centroid by the distance e = 3"
The moment Pe will produce a shear force on the connectors, value of the ...
