Soln = for chaing bolting
An=(b-ndo)8
=(210-4 X 18)8
An=1104 mm$^{2}$
For zig zag bolting
1) along path AB & FG (2 holes) net area will be
An=$(b-nda)t+(\frac{\sum p^{2}}{4g})$
=(210 X 2 X 18)8+0
=1392 mm$^{2}$
2) Along path cnf (three holes)
An=(h-nda) X t+$\frac{\sum p^{2}}{4g}$
=(210-3 X18)X8+0
An=$1248mm^{2}$
3) …
