An A$572$ Gr$.50$ L$6$x$3-1/2$x$1/2$ is used as a tension brace. Assume two lines of $\frac{3}{4}-$inch bolts are used to connect the brace to gusset plate. Add $\frac{1}{16}-$in to hole diameter for damage from punching.

Determine the maximum permissible shear lag factor that can be used to compute the effective net area of the angle.
