To analyze two built-up members that have the same geometry but
are fastened differently, determine the maximum applicable shear
force on each cross section, and determine the adjustment in
spacing between the weaker member’s fasteners that would allow the
member to support the equivalent maximum shear force of the
stronger member.
The two cross sections shown below, (a) and
(b), are subjected to a vertical shear force as shown. The
members are fastened by nails that can support a load...
