For a WT$850$ attached through a flange to a $12\frac{3}{4}$ in$.$ plate with $8-\frac{7}{8}$ in$.$ bolts at a $3$ in spacing

along the member placed in two rows of $4($as shown$),$ determine: the shear lag factor, effective net

area, and controlling limit state. By how much $(\%)$ does the limit state control over the others? Bolts

are $2"$ in from the edges. You can ignore block shear.
